Answer:the Length is 22.5 inches, and width is 7.5 inches.
Step-by-step explanation:
Step 1
The perimeter of the rectangle is given as
P = 2L + 2W
We were given tha length is 3 times the width,
so L = 3 W
Replacing L by 3W in the equation of the perimeter becomes
Step 2
P = 2L + 2W
2(3W) + 2W = 60
6W + 2W = 60
8W =60
W = 60 /8
W = 7.5
Snce L = 3W
L= 3 (7.5)
L = 22.5
Therefore the Length is 22.5 inches, and width is 7.5 inches.
