Question

The width of a rectangle measures (3v-3w) centimeters, and its length measures (5v-9w) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

Answer 1

Answer: The Perimeter of the rectangle, P= 16v −24w

Explanation:

Perimeter of a rectangle = 2( L +W) = 2L + 2W

The width of a rectangle is given as (3v-3w) centimeters,

its length is given as (5v-9w) centimetres

The Perimeter,P will now be = 2L + 2W

P=2( 3v-3w) + 2( 5v-9w)

P=6v −6w + 10v - 18 w

adding like terms

P=6v + 10v −6w −18 w

P= 16v −24w
