Question

The area of a square living room is 1225 square feet. What is the perimeter of the room?

Answer 1

140 ft

Explanation:

Here, A = 1225 ft² = s², where s represents the length of one side of the room. Here, s = √( 1225 ft² ) = 35 ft.

Thus, the perimeter, P = 2L + 2W, is 4(35 ft) = 140 ft

Answer 2

The area of a square is length*width and since a square has the same side measurements, √1225 or 35 is one side. (35 * 35 = 1225)

There are 4 sides so 35*4 = 140ft² as the perimeter

I hope this helps!
