Answer:
Step-by-step explanation:
Let one side be x
Then the equal sides be 2x
The base is 6/5 times of x
Then base is 6x/5
Perimeter is 32
Perimeter = 2x + 6x/5
32 = 2x x 5/1 x 5 + 6x/5
32 = 10x/5 + 6x/5
32 = (10x + 6x)/5
32 x 5 = 16x
160 = 16x
160/16 = x
x = 10
The equal sides are 10, 10
Base = 10 x 6/5
=2 x 6
=12
