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?
(Points : 4)
23 in.
29 in.
32 in.
35 in.

Answer 1

2w + 2L = perimeter so
perimeter is 58
the given length is 5+ 3w plug that in the formula

2w + 2(3w+5) = 58
2w + 6w + 10 = 58 we mult thru parentheses
8w = 48 we combined the the w terms and subtracted 10 from both sides

divide 8 both sides that will give you the width plug it back in the
2w + 2L = perimeter to find the length

if you need help ask

Answer 2

23 in
Solve: 2 (w + 3 w + 5) = 58
w = 6
Length = 3w + 5 = 18 + 5 = 23
