Answer:

Step-by-step explanation:

Formula

P = 2w + 2L

w = x + 3

L = 2(x + 4)- (x + 4)                          Remove the brackets on both terms

Solution

L = 2x + 8 - x - 4                              Combine like terms

L = x + 4                

P = 2L + 2w

P = 2(x + 4) + 2(x + 3)                       Remove the brackets

P = 2x + 8 + 2x + 6                           Collect like terms

P = 2x + 2x + 8 + 6                           Combine

P = 4x + 14

Answer

Perimeter = 4x + 14
