SO! how do I solve this problem in inches?
A triangle with sides that measures 2 1/2 ft., 20 in., and 1/2 yd. Answer in inches

1. Ms. Sue

Find the Perimeter, sorry.

3. Ms. Sue

Ahh!

The perimeter is the distance around an object.

For a triangle, add the lengths of the three sides.
2 1/2 feet = 30 inches
1/2 yard = 18 inches
