Question

A rectangle is formed by placing 2 identical squares side by side. The area of the rectangle is 98 cm2. What is the perimeter of one square

Answer 1

The rectangle area is 98. So if you split it in half, you would get 2 squares. Half of 98 is 49.

If it is now a square, you now simply know, that 7*7=49. Meaning that The sides of the square are 7 each.

7 times the 4 sides equals 28. So the perimeter of one square is 28.
