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

    Answer WHAT? Area? Perimeter? Or?

  2. Ann

    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
