This isosceles triangle has two sides of equal length, a, that are longer than the length of the base, b. The
perimeter of the triangle is 15.7 centimeters. The
equation 2a + b = 15.7 models this information.
If one of the longer sides is 6.3 centimeters, which
equation can be used to find the length of the base?
