find side and area​

Answer 1

Step-by-step explanation:

I think it's a square so I will give my answer accordingly.

Perimeter of a square is four times its side

So, 4(12x - 120) = 320

12x - 120 = 80

12x = 200

X = 200/12 = 50/3

Therefore, one side = 12x - 120 = 12(50/3) - 120 = 200-120 = 80m

Area is the square of side = 80×80 = 6400m²
