Question

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?

Answer 1

Answer:

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

Answer 2

Answer:

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 data:

'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
