The length of a rectangle is (x+4) inches long and the width is 4 2/5 inches. If the area is 28 3/5 square inches wight and solve an equation to find the length of the rectangle

Area = length times width

Length = x + 4

Width = 4_2/5, which we can write as the improper fraction 22/5.

Area is given to be 28_3/5, which can be written as 143/5.

Here is the set up:

(143/5) = (x + 4) (22/5)

Take it from here.
