Sonya wants to sew ribbon along each side of a square pillow. if the pillow has an area of 144 square inches, how much ribbon must she buy to have the exact amount that she needs? enter your answer in the box.

Area is L * W
In a square, it’s just S * S or Side * Side.
Since both sides are the same length, we need to find two values that multiply to be 144. 12 is the square root of 144, so 12 * 12 is 144, and are also the side lengths we are looking for. So the side length of this square is 12. There are 4 sides to this pillow, so 12 * 4 will give us the perimeter. 12 * 4 = 48. So each side length added together is 48 in total and therefore, Sonya needs 48 inches of ribbon.

1. 8 or -82. 14 or -143. -11, -3, 0, 7, 10
