Perimeter of the rectangle

Question

A rectangular garden has dimensions expressed by 4x and 3x - 1.

Write and simplify an expression for the perimeter of the rectangle.

What is the perimeter of the rectangle if x = 2 metres?

Answer 1

4x + 3x-1 = half the perimeter = P/2

P = 2(7x-1) = 14x-2

P = 14x-2

if x = 2

P = 14(2)-2 = 28-2 = 26 meters

with dimensions 4x and 3x-1 = 4(2) and 3(2)-1 = 8 and 5

8+5 = 13 = 26/2
