Question

An isosceles triangle has two sides of equal length, a, and a base, b. The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7.

Answer 1

Explanation:

Yes you are correct. You cannot go any further because you have 1 equation with 2 unknowns. Any answer (within limits) is possible. For example

if a = 2 b= 11.7

if a = 3 b = 9.7
