Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long. Maria has 3/4 foot of trim left. What was the length of the trim when she started. Enter your answer in yards.

We have been given that Maria put trim around a banner that is the shape of a triangle. Each side is 21 inches long.

The amount of trim will be equal to perimeter of triangle. The perimeter of given triangle will be 3 times each side length that is  inches.

Now we need to convert 63 inches into feet.  

12 inches = 1 feet

63 inches =   feet = 5.25 feet.

We are also told that Maria has  foot of trim left, so total length of trim would be trim used plus trim left that is  feet.

Since we need to find length of trim in yards, so we will convert 6 feet into yards.

3 feet = 1 yard

6 feet =  yards = 2 yards
