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.

Multiple answers are possible

Step-by-step explanation: I can't give you a concrete answer without more information.

For example, a could equal 5 and b could equal 5.7 in one situation

And in another, a could equal 6 and b could equal 3.7

Both of those examples are hypothetical and possible, but not surely correct.

Either I need more information or I misunderstood your question, in that case that's my bad.
