Best answer 3 votes 3 votes Option D. 88 Area of a Rectangle = l × b [ Given that area = 680 sq feet, one side = 20 feet(say l) ] b = $\frac{680}{20} = 34$ feet The perimeter of a Rectangle = 2(l + b) only three side is needed i.e. 2b + l = 88 feet Madhav answered Oct 2, 2020 • selected Oct 2, 2020 by gatecse Madhav 3.6k points comment Share See all 0 reply Please log in or register to add a comment.
