The dimension of the selected floor tiles is 1 m × 2 m. Solution: Given, Height = 80 m and Width = 60 mĪt the cost of ₹ 3 per m 2, the cost for painting 4800 m 2 is 4800 × 3 = ₹ 14,400ĥ) A floor whose length and width are 60 m and 40 m respectively needs to be covered by rectangular tiles. If a painter charges ₹ 3 per m 2 for painting the wall, how much would it cost to have the whole wall painted? Ĥ) The height and width of a rectangular wall are 80 m and 60 m respectively. Solution: Given, Height = 20 cm and Area = 240 cm 2. ģ) The height of a rectangular screen is found to be 20 cm. Therefore, the area of the rectangle = 106.8 cm 2. Solution: Given, Height = 89 mm = 8.9 cm, and Width = 120 mm = 12 cm Ģ) A rectangular board has a width of 120 mm and a height of 89 mm. Therefore, the area of the rectangle = 80 cm 2. Solution: Given, Height = 20 cm and Width = 4 cm Problems Relating to the Area of a Rectangleġ) Find the area of a rectangle whose height is 20 cm and width is 4 cm. The area of rectangle ABCD will be the sum of the triangle ABC and ADCĪrea of rectangle ABCD= Area of triangle ABC + Area of triangle ADCĪrea of rectangle ABCD= 2 x Area of triangle ABCĪrea of rectangle ABCD = Length x Breadth The lengths and breaths of a rectangle ABCD are AB, CD BC, and AD respectively.Ī diagonal AC is drawn in a rectangle ABCD.ĪC will divide the rectangle ABCD into two triangles ADC and ABC which are congruent. The result will be given in square units.Įxample- The length and width of a rectangle is 8 units and 4 units respectively. Multiply the length with the width of the rectangle. To find the area of a rectangle follow the steps given below-įrom the given data, note the dimensions of the length and width. The mathematical formula used to calculate the area of a rectangle within its boundary is-Īrea of a rectangle= (Length x Breadth) square unitsĪrea of a rectangle is given by the products of its length and width(breadth). Hence for a square, the area is the square of its sides. In a square, since all the four sides are equal, Area = w × h becomes The area of the rectangle is Area = w × h The formula to calculate the area of a rectangle is given asįor example, if a rectangle is 8 m wide and 3 m high, The area is simply the width of a rectangle times height. To find the area of a rectangle, we simply need to multiply its length by its width. Area of larger shapes, like fields or cities is measured in square kilometers, hectares, or acres. The area is usually measured in units like square meters, square feet, or square inches. The area is a two-dimensional property, which means it contains both length and width. It is the number of square units inside the polygon. The area of any polygon is the amount of space it occupies or encloses. We can also say that a rectangle with all four sides equal to each other is a square. The rectangle is also a parallelogram, which means the opposite sides of the rectangle are perfectly parallel to each other. Since the opposite sides of the square are equal, the square can also be considered as a rectangle. In a rectangle, only the opposite sides of the quadrilateral are equal.
In a square all the four sides of the quadrilateral are equal. The two types of equiangular quadrilaterals are squares and rectangles. They are also called equiangular quadrilaterals since all their angles are equal. If all four sides of the quadrilateral are 90°, they are right-angled quadrilaterals. Quadrilaterals can be further classified into concave quadrilaterals, convex quadrilaterals, and right-angled quadrilaterals based on the angles they contain. A polygon with four sides is called a quadrilateral or tetragon. Polygons are classified based on the number of edges or vertices they have. A polygon has an equal number of edges and vertices. The points where the line segments intersect are called vertices.
Edges are also called sides, and they are nothing but the line segments which make up the polygons. The polygons are classified by the number of edges they have. There are many different types of polygons, some of them being triangles, quadrilaterals, pentagons hexagons etc. Some examples of rectangle shapes are- mobile screens, blackboard, doors, etc.Īny closed shape made up of at least three-line segments is known as a polygon. The area of a shape is measured in terms of the number of square units such as square feet, square inch, square centimeters and so on. Therefore, the area of a rectangle is equal to the number of unit squares that can fit into the boundaries of a rectangle. The number of unit squares that can fit into any shape, is the area of that shape. A quadrilateral whose parallel sides are equal to each other and all the vertices are perpendicular to each other is called a rectangle.
