Question

mandy's square quilt measures 99 inches on each edge. how many yards of trim does she need to buy to go around the entire quilt?

Answer 1

To find the perimeter just add all the sides together. Since it's a square, we can do 99*4. That gives us 396 inches
But wait! They want us to answer in yards. Since there are 3 feet in a yard and 12 inches in a foot, there are 36 inches in a yard. 396/36 is 11, making the answer 11 yards

Answer 2

There are 36 in in a yard

36 in ------> 1 yd


99 in ------> x

x = (99)(1)/36
x = 2.75
99 inches equals 2.75 yards and that is the amount of trim that Mandy needs to go around the entire quilt
