To find the lenght of the rectangle given its area and its width.

Area = x%5E2+%2B+50x

width = x units.

To find the lenght.. ??

Area = length * width

x%5E2+%2B+50x+ = length * x

x(x + 50) = length * x

==> (x + 50) = length


Hence, the length of the rectangular painting is (50 + x) units.

Thus, the solution
