---
x = length
y = width
---
2x + 2y = 84
x = y + 24
---
put the system of linear equations into standard form
---
2x + 2y = 84
x - y = 24
---
copy and paste the above linear system in standard form into this matrix-method solver:

solution:
x = length = 33 ft
y = width = 9 ft
area = xy
area = 33*9
area = 297 sq.ft
