Arectangle has a perimeter of 20m express the area

Because the perimeter is 20m, the short sides of the rectangle can be 2m and the long sides are 8m (since 2m + 2m + 8m + 8m = 20m)

And since we figured out 2 of the side lengths (2 and 8), we can figure out the area

2 x 8 = 16

Therefore, the area is 16m

see explanation

Step-by-step explanation:

Angles 1 and 8 and angles 2 and 7 are alternate exterior angles.

They are on opposite sides of the transversal and outside the parallel lines.
