Robert wants to put lights around the edge of his deck. the deck is 40 feet long and 29 feet wide. how many yards of lights does he need?

He would need a total of 46 yards of lights. If he wants to put lights around the edge of his yard he would have to find the permitted which is adding up all the measurements of the sides. So since one side of his deck is 40 the side directly across from it is 40 and same with 29 so you would add up 40+40+29+29=138 feet and since there is 3 feet in one yard then you would divide 138/3 to get 46 yards
