no. you need to think of it this way:
to find the area of a square, the formula for that is length x width.
so for the square lot, every side is equal to 900 because squares have all equal sides.
to find the perimeter, you only need to add up all the side lengths. in this case. it would be 900+900+900+900. i’m adding it 4 times because a square lot has 4 sides.
the correct way to solve and to find the answer is:
900+900+900+900=3,600
The perimeter of the lot is 3,600m.
