The Area of a rectangular carpet is 18 m2. The length of the carpet is 3m longer than the width. How long is the carpet
we have that
the area of a rectangle is equal to
A=L*W
In this problem we have
A=18 m2
L=W+3
substitute the given values
18=(W+3)*W
solve for W
18=w^2+3w
w^2+3w-18=0
solve the quadratic equation by graphing
see the attached figure
the solutions are
w=-6 and w=3
Find the value of L
L=W+3
L=3+3
L=6
