You can put this solution on YOUR website! ---
x = length
y = width
---
x = y + 8
2x + 2y = 80
---
put the system of linear equations into standard form
---
x - y = 8
2x + 2y = 80
---
copy and paste the above standard form linear equations in to this solver:

solution:
x = length = 24 in
y = width = 16 in
a = 16*24 = 384 sq.in
