Arancher has a roll of fencing to enclose a rectangular area. the table shows how the area that the rancher can enclose with the fencing depends on the width of the rectangle. width (w)ft area (a) ft2 10 900 20 1,600 30 2,100 which quadratic equation gives the area a of the rectangle in square feet given its width in w feet? a. a(w)= -w to the power of 2+200w b. a(w)= -w to the power of 2+100w c. a(w)= w to the power of 2+40w d. a(w)= w to the power of 2+90w
