Question

lauren is making a design with tiles, which are shaped like squares. she cuts yarn to go around each square. how many inches of yarn does she need for a square with sides that are 6 inches long? (2 - 5)
inches on one side 2 3 4 6
inches of yarn 8 12 16?
a 20
b 22
c 24
d 28

Explanation:

Step1: Recall perimeter formula

The length of yarn needed is the perimeter of the square. The formula for the perimeter \(P\) of a square is \(P = 4s\), where \(s\) is the side - length of the square.

Step2: Substitute side - length value

Given \(s = 6\) inches. Substitute \(s=6\) into the formula \(P = 4s\), we get \(P=4\times6\).

Step3: Calculate the result

\(4\times6 = 24\) inches.

Answer:

C. 24
