The hamers plan to add a rectangular shaped pool to their backyard/ the pool will have a 4-foot deck around it, as shown in the diagram below.

See the attachment. I find it easier to split up the deck as such. We can now take areas of these 4 new rectangles that we made that we can find the dimensions for easily.

Left rectangle: 4*33 = 132 feet

Right rectangle: 4*33 = 132 feet

Top rectangle: 4*15 = 60 feet

Bottom rectangle: 4*15 = 60 feet

Add up all these areas to find the total area of the deck:

132 + 132 + 60 + 60 = 384 feet total.

This is answer C.

30

5y = 5 * 6 = 30
