Question

Find the length of each side of a square park whose area is the same as the area of rectangular field of dimensions 45m × 20m

Answer 1

Area of rectangle (length x breadth) = 45m x 20m
= 900 square meters.

Area of square = (side x side)
Side^2
Area of square = Area of rectangle

900 square meters = side^2
Square root of 900 square meters = side (Reason - finding the square root of values on both sides of equation)

30 meters = side

Therefore, side of the square is 30m
