Answer:

Step-by-step explanation:

Perimeter = 2l + 2w

With the given statement, the width of the rectangle is 4 meters less than the

length,

w = l - 4

sub that in the first equation,

Perimeter = 2l + 2(l - 4)

Perimeter = 2l + 2l - 8

Perimeter = 4l - 8

Since perimeter is 72m,

72 = 4l - 8

4l = 80

l = 20m
