The area of a rectangular wall of a bran is 96 square feet. Its length is 4ft. longer than the width. Find the length and width of the wall.
L(ength) = W(idth) + 4
L * W = 96
Substitute W+4 for L in the second equation to find W. Insert that value into the first equation to find L. Check your answers by inserting both values into the second equation.
I hope this helps. Thanks for asking.
