Question

Maria put trim around a banner that is the shape of a triangle. Each side is 22 inches long. Maria has 1/2foot of trim left. What was the length of the trim when she started? Write your answer in yards

Answer 1

Maria had 2 yards of trim when she started.

Step-by-step explanation:

Step 1:

All of the sides of the triangle is 22 inches long each.

The total length of the sides of the triangle $= 3(22) = 66.$

So the total length of the trim for the banner is 66 inches long.

If Maria still has $\frac{1}{2}$ a foot of trim left, she had 6 inches of the trim left.

The length of the trim when she started$=66 +6 = 72$ inches.

Step 2:

Now we need to convert the 72 inches into yards.

We have 1 inch = 0.0277778 yards.

So 72 inches $= 0.0277778(72) = 2.$

So Maria had 2 yards of trim when she started.
