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

based on context clues you gave i'm assuming the answer would be c.

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
