Question 286170
L = length
W = width
A = area = L*W = 6 sq. ft
.
L = W+2
.
Substituting...
.
(W+2)*W = 6
W^2 + 2W = 6
W^2 + 2W -6 =0
.
We cannot factor it, so use the quadratic equation...
.
*[invoke quadratic "x", 1, 2, -6 ]
.
A negative width is nonsensical, so we'll go with W = approximately 1.6457.
Substituting W=1.6457, we can find L.
.
L = W+2 = 1.6457 + 2 = 3.6457
.
Checking this solution, is the Area = 6?
.
1.6457*3.6457 =5.9997, which within the rounding error caused by using the approximation W = 1.6457.
.
Done.
