Question 894752
each of the equal sides of an isosceles triangle is three times as long as the base. if the perimeter is 84 inches, find the length of the base
--------------
Let the base be "x".
Each of the equal sides is "3x".
----
Equation:
x + 3x + 3x = 84
7x = 84
x = 12 inches (length of the base)
