Answer 1

He would need a total of 46 yards of lights.

Explanation:

Answer 2

144 feet of lights

Explanation:

This is because when the problem says “around” it refers to perimeter. The problem also gives you the length and width of the deck, which is what you will need for the perimeter formula.

Perimeter= length•2 + width•2

Now we insert the length and the width.

Perimeter= 46•2 + 26•2

=92+52

=144 feet
