Question

find the breath of rectangle whose are\ is 20 squad CM and length 5cm​

Answer 1

Answer:

Area of each small square = 1 sq cm

Area of rectangle in figure 2 by counting the squares = 10 sq. cm

Area = 10 square cm

Length of rectangle = 5 cm

Breadth of rectangle = 2 cm

Area = 5 × 2 = 10 sq. cm

Hence, area of rectangle = length × breadth

A = l × b where, A is the area, l and b are length and breadth of a rectangle.

Area of Rectangle

From the above figure, it is clear that we can divide this rectangle into 20 squares of sides 1 cm each. So, the area = 20 cm2

Thus the area of the rectangle = 5 cm × 4 cm

                                            = 20 cm2
