the length of a rectangle is three times more than the length. the perimeter is 48in. what are the width and length of the triangle?

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
