The perimeter of the square towel is 44 cm, which is found by first determining the side length of the square cloth (11 cm) and then using the perimeter formula for a square.
The question asks us to find the perimeter of a square towel after using a fringe from a 121-cm² square cloth to trim one side.
First, we determine the side length of the square cloth by calculating the square root of its area. In this case, √121 cm² is 11 cm.
The perimeter of the square towel can then be found knowing that the fringe is equal in length to one side of the towel.
Therefore, each side of the towel is also 11 cm.
Using the formula for the perimeter of a square (P = 4 × side length), we calculate the perimeter as follows: P = 4 × 11 cm = 44 cm.
So, the perimeter of the square towel is 44 cm.
