Question

The perimeter of a square is twice the perimeter of a rectangle. if tge perimeter of the square is 72cm and the length of the rectangle is 12cm what is the difference between the breadth of the rectangle and the side of the square

Answer 1

Now,
2(l+b) = 2(4a)
2(12+b) = 72
24 + 2b = 72
2b = 48
b=24 ✅

8a = 72
a = 9 ✅

difference between breadth of rectangle and side of a square will be,
b - a = 24 - 9 = 15 answer !!
