Step-by-step explanation:
Length of rectangle = 20cm
Breadth of Rectangle = 5cm
Area of Rectangle = L*b
= 100cm²
Given,
Area of Rectangle = Area of square
100cm² = side²
side of square = 10cm
Perimeter of rectangle = 2(L + b)
= 2 * 25
= 50cm
Perimeter of square = 4*side
= 4*10
= 40cm
Difference between perimeter
= 50 - 40 = 10cm
Answer = D)
