w width
L length
system%28L=5%2Bw%2CwL=22%29


w%28w%2B5%29=22
w%5E2%2B5w-22=0

Formula for general solution of quadratic equation is used:

w=%28-5%2Bsqrt%2825%2B4%2A22%29%29%2F2, the PLUS form will be necessary.
w=%28-5%2Bsqrt%2825%2B88%29%29%2F2
highlight%28w=%28-5%2Bsqrt%28113%29%29%2F2%29

L=22%2Fw
L=22%2F%28%28-5%2Bsqrt%28113%29%29%2F2%29
