Question

The length of a rectangle is 5 more than 3 times its width. The perimeter of the rectangle is 58 inches. What is the length of the rectangle?

Question 10 options:

23 in.


29 in.


32 in.


35 in.

Answer 1

so let the width be w

then the length is 3w + 5

to the perimeter is

P = 2( l + w)

so using the information


P = 2(w + 3w + 5)

or

P = 8w + 10

you know the perimeter

so

58 = 8w + 10

solve for w

then from there you can find the length of the rectangle
