Question

The perimeter of an isosceles triangle is 71 centimeters. The measure of one of the sides is 22 centimeters. What are all the possible measures of the other two sides? Show your work.

Answer 1

An isosceles triangle has 2 sides the same length and 1 side of a different length
 

so if the 22 is the identical length then you would have another side of 22
 and the 3rd side would be 71 - 22 -22 = 27 cm
 so you could have 22 and 27

 if the 22 is the odd length side then you would have 71 - 22 = 49 / 2 = 24.5
so you could have 24.5 and 24.5
