Question

Write an algebraic expression for the perimeter of a rectangular garden with a width of 3 metres and a length of 2y metres. Simplify your expression, and determine the perimeter of the garden if y = 6.

Answer 1

Answer:

P = 2(2y+3)

P = 30

Step-by-step explanation:

P = 2 (L+W) or P = L + L + W + W

P = 2 (2y+3)

P = 4y+6

Plug in 6 for y.

P = 24+6

P = 30
