Expert Answer
Given that:
Perimeter of square = Perimeter of rectangle.
Length (l) of the rectangle = 10 m
Breadth (b) of the rectangle = 8 m
Perimeter of the rectangle = 2 x (l + b)
= 2 x (10 + 8)
= 2 x 18
= 36 m
So, perimeter of the square = 36 m
Formula for perimeter of square:
Perimeter of square = 4 x s
36 = 4 x s [swap both sides]
4 x s = 36
s =
= 9 m
Thus, the side of the square is 9 m.
Perimeter of square = Perimeter of rectangle.
