Hi,

the length of a rectangle is 5 more than the width green%28x%29. length is ((x+5)

if the perimeter is 42 ft, what are the dimensions of the rectangle.



 P = 2(x+5) + 2x = 42ft

      2x + 10 + 2x = 42ft

           4x = 32ft

            x = 8ft, the width.  The length is 13ft

  26ft + 16ft = 42ft
