Question

A rectangle has side lengths (2x - 5) meters and (2x + 6) meters. write a linear expression in simplest form to represent the perimeter. find the perimeter if the value of X is 12 m.

Answer 1

Answer:

P = 8x + 2    When X is 12, P is 98 m

Step-by-step explanation:

P = 2(L + W)

P = 2[(2x - 5) + (2x + 6)]

P = 2[4x + 1]

P = 8x + 2

P = 8(12) + 2

P = 98 m
