Question

7.
The area of a square garden is 900m2. Find
its perimeter.​

Answer 1

120 square meters

Explanation:

Since area is base times height and this is a square, we know all sides are the same length. Take the square root of 900 and you will get 30, meaning each side is thirty meters long. 30 x 4 = 120, that’s your perimeter. Hope this helps! I’m on my phone, so sorry if this explanation is hard to read. Feel free to ask any questions!

Answer 2
