Step-by-step explanation:
Given,
Length = 40m
Breadth = 30m
Perimeter of rectangle = Perimeter of Square
We know that,
Perimeter of rectangle = 2(l+b)
= 2 (40 + 30)
= 2 x 70
= 140cm
Now we know that perimeter of rectangle = perimeter of square. So,
Perimeter of square = 4 x each side = 140cm
Let each side be 'x', so
4x = 140cm
x = 140/4
x = 35cm
Therefore the side of the square = 35cm
