Robert wants to put lights around of his deck. The deck is 49 feet long and 23 feet wide. How many yards of lights does he need?

  48

Step-by-step explanation:

If we assume that lights are put on all four sides of the rectangular deck, the perimeter length of the deck is ...

  P = 2(L+W) = 2(49 ft + 23 ft) = 2(72 ft) = 144 ft

There are 3 ft in each yard, so this length is ...

  (144 ft) × (1 yd)/(3 ft) = 48 yd

Robert needs 48 yards of lights.

2 and 1.

step-by-step explanation:

plug in each answer. 0 doesn't work, 1 does. so does 2. 4 doesn't:

0 = 1 is not true.

2 = 2 is true.

4 = 4 is true.

8 = 16 is not true.

hope this !
