let W in terms in L in equation 2 and it comes up to this W= sqroot(20 + L^2) then substitute the W from the equation 2 to equation 1 and the equation 1 becomes 192= L * sqroot(20 + L^2) solving L using algebra skill 192/L = sqroot(20 + L^2) square both sides to cancel the sqroot 36864 =L^2( 20 + L^2) distribute L then 36864 = 20L^2 + L^4 then further simplification and algebra skills like an animal !! you will get the value of L L = 13.5 rounded off or 13.5 inches then substitute L to equation 1 192= (13.5)W then W = 14.2222 or 14.2 inches!! I hope it helps!!!
