Question

The width of a rectangle measures (3u−4v) centimeters, and its length measures(10u+2v) centimeters. Which expression represents the perimeter, in centimeters, of the rectangle?

1) −4+26u+4v
2) 26u−4v
3) 13u−2
4) 26u−4

Answer 1

Answer: Choice 2

26u−4v

Work Shown:

W = width = 3u-4v

L = length = 10u+2v

P = perimeter of the rectangle

P = 2(L+W)

P = 2(3u-4v+10u+2v)

P = 2(13u-2v)

P = 26u-4v
