Explanation:
Given parameters
Base of the isosceles = x
Length of leg = 4x - 4
Unknown:
Perimeter of triangle =100
Unknown:
The perimeter of a triangle is the sum of its sides;
An isosceles triangle has two equal length of leg;
So;
x + 2(4x - 4) = 100
x + 8x -8 = 100
9x - 8 = 100
9x = 100 + 8
9x = 108
x = 12
