Question

Someone plz help desperateeeeee

Answer 1

We are told that Tristan is planting a garden that's square shaped and its area is 64 square meters.  Because 8 * 8 = 64, we have a square where each side is 8 meters along.

From an algebra point of view, where s is a side of the square,

s² = 64

s = 8 or s = -8 by taking square roots of both sides

s = 8 by discarding the -8 (lengths cannot be negative)

Now that we know a square's side we need its perimeter. Each side is the same, so a square's perimeter is four times a side.

4 * 8 = 32, which is our perimeter.

Therefore 32m² of material are needed.
