---
x = length
y = width
---
2x + 2y = 98
x/y = 5/2
---
put the system of linear equations into standard form:
---
2x + 2y = 98
x = (5/2)y
---
2x + 2y = 98
x - 2.5y = 0
---
copy and paste the above linear system in standard form into this matrix-method solver:

solution:
x = length = 35 ft
y = width = 14 ft
