To cover a rectangular region of her yard, Penny needs at least 170.5 square feet of sod. The length of the region is 15.5 feet. What are the possible widths of the region?
L=length=15.5 ft; W=width; A=area=>170.5 sq ft
L*W=>170.5 sq ft Divide each side by L
W=>170.5 sq ft/L
W=>170.5 sq ft/15.5 ft=>11 feet
ANSWER: To cover at least 170.5 sq ft. the width must be at least 11 feet.
