- Math, not Summer Creek -
**Reiny**, Sunday, June 16, 2013 at 9:31am2x + y = 38 -----> y = 38-2x

the base is 8 inches shorter than the length of a leg

y = x-8

x-8 = 38-2x

3x = 46**x = 46/3 inches**

then y = 38 - 92/3 = 22/3 inches

check:

perimeter = 2x+y = 92/3+22/3 = 38

difference between leg and base

= 46/3 - 22/3 = 8
