I misread the question.

3w=l

2l+2w=65.6

8w=65.6

w=8.2

l=24.6

Adalynn · Answer 2

The width is 8.2

Perimeter = 2W + 2L (there are four sides of a rectangle, two longer sides, two shorter, W and L)

65.6 = 2W + 2L

L = 3W so substitute 3W in for L

65.6 = 2W + 2 (3W)

65.6 = 8W

W = 8.2 cm

L = 3 (8.2)

L = 24.6cm
