I’m not extremely good at math but I think you need to make -x-y=1 into y=mx+b form and then solve your new equation!
C=2

r
A=

r<span>²
C=2</span>

r=58

2r=58
r=29
A=

r<span>²
A=29</span><span>²</span>

A=841
1 foot = 12 inches
2 x 12 = 24 +3 = 27 inches
3 x 12 = 36 +5 = 41 inches
27*41 = 1107 square inches
1107 * 0.35 = $387.45
