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

2a + b = 15.7 

length a is longer than b.
a = 6.3

2a + b = 15.7
(2*6.3) + b = 15.7
12.6 + b = 15.7
b = 15.7 - 12.6
b = 3.1

therefore the base length is 3.1 cm
