Question

The equation p^2 = 9A represents the perimeter, P, of square with area, A. A square stained - glass window window has an area of 4ft^2. What is the perimeter of the window?

Answer 1

P = 8ft

Explanation:

Since the window is a square and has an area of 4, since neither length or breadth can be negative, the length and breadth are 2 ft.

perimeter = 2l + 2b

l = 2ft

b = 2dt

2(2ft) + 2(2ft) = 4ft + 4ft = 8ft

P = 8ft
