I need help. A rectangular field is to be enclosed with 1,140 feet of fencing if the length of the field is 70 ft longer than the width then how long is the field?
1140= length times width 1140= lw 1140= (w+70) + w 1140=2w + 70 Subtract 70 from both sides 1070=2w Divide both sides by 2 535=w 605=l because l is w+70
