1).- P = 2(W + L)-------------OR-------------- P= 2W +2L (distributing)

where:
p= perimeter
w= width
l= length

They tell you that &quot;the length is 2 meters more than twice it width&quot;

2).- L = 2 + 2W

If we substitute (2) in (1), then:

P = 2W + 2 ( 2 + 2W)
P = 2W + 4 + 4W
P = 6W + 4

We also know that the perimeter is 40 meters, so:
 P = 40 = 6W + 4

Solving for W, you get:

40 = 6W + 4
36 = 6W

W = 6.

But we want to know what L equals. We go back to equation 2 and subtitue W =6.

L = 2 + 2(6)

L= 14

WHICH IS TRUE..

P = 2(6) + 2 (14)
P = 12 + 28
P = 40
