Alejandra plans to sew fringe on a scarf. The scarf is shaped like a rectangle. The length of the scarf is 56 inches. The width is one half the length. How much fringe does Alejandra need?

168 inches

Step-by-step explanation:

The amount needed is the perimeter.

Perimeter = 2 (L+W)

L = 56

W = 28

Perimeter = 2 (56+28) = 168inches

168 inches

Step-by-step explanation:

First of all you need to find the perimeter of the rectangle. It can be determined by,

P (perimeter) = 2L (length) + 2W (width)

Given dа ta:

'L' length = 56 inches

width = 1/2 0f 56 = > 28 inches

therefore, P = 2 (56) + 2 (28)

P = 112 + 56

P = 168 inches

Therefore she needs 168 inches fringe
