The area of a rectangle is 60 square inches. if the length is 3 times the width, then find the dimensions of the rectangle. round off your answers to the nearest hundredth

Length (L): 3w

width (w): w

Area (A) = L x w

        60 = (3w)w

        60 = 3w²

          20 = w²

         +/- √20 = w

since width cannot be negative, disregard  - √20

w = √20  = 4.47

Length (L): 3w    = 3(4.47)  = 13.41

width = 4.47 inches, length = 13.41 inches   

width=4.16 meters, length=6.48 meters

the 4th choice is the correct one
