Answer:
<h2>Leg length = 8.5</h2><h2 />
Step-by-step explanation:
let x represent the leg length
if we use the Pythagorean theorem we get:
x² + x² = 12²
then
2x² = 12²
Then
x² = 144/2 = 72
then 
x = √(72)
  =8,485281374239

The sum of b and f is b+f
Three times this sum is 3(b+f)
 
        
             
        
        
        
75 : 15 = x : 13
15 x = 75 · 13
15 x = 975
x = 975 : 15
x = 65
