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 equa
tion to solve is 2a + b = 15.7.
Which lengths make sense for possible values of b?
1 answer:
Given,
Perimeter = 15.7 inches
2a + b = 15.7
b = 15.7 - 2a
Hence, (15.7 - 2a) would be the length of the base.
