Question

The length of a rectangular picture is 5 inches more than 3 times the width. Find the dimensions of the picture if the perimeter is 74

Answer 1

Width=8, Length=29

Explanation:

Length=L, Width=W

L= (3W+5)

Perimeter= 2L+2W

W+W+3W+5+3W+5=74

8W+10=74

-10 -10

8W=64

W=8

Substitue 8 in for W

L=3(8)+5

L=29
