Answer:
Length = 18 inches
Width = 6 inches
Step-by-step explanation:
The length (l) of a rectangle is three times more than the width (w).
The perimeter of the rectangle is 48 inches.
Let's say the width of this rectangle is x inches.
The length will be 3x inches.
Perimeter of a rectangle = 2l + 2w
So 2(3x) + 2x = 48 inches
6x + 2x = 48 inches
8x = 48 inches
x = 6 inches
So the width of the rectangle is 6 inches and the length is 3 × 6 = 18 inches
