Two lines that intersect at 90 degrees are considered perpendicular to each other.
Answer:
D-Square
Step-by-step explanation:
That describes a square, so the answer a square.
A and D I think or it may just be A
Perimeter of a parallelogram = 2(l + w). But w = l - 4
Therefore, 72 = 2(l + l - 4) = 2(2l - 4) = 4l - 8
4l = 72 + 8 = 80
l = 80/4 = 20
w = 20 - 4 = 16
Therefore, length = 20 meters and width = 16 meters
