Question

The area of a square is greater than the area of the circle by 12 cm^2. Find the length of the side of a square if the area of the circle is 36 cm^2?

Answer 1

Adding 12 to the circle area is equal to the square area.

Or

s2 = 12 + A

Where

s = side of square

A = area of circle

So

s2 = 12 + 36

s2 = 48

Solve this for s to get the side length
