The area of the only deck is 528 ft²
<u><em>Explanation</em></u>
The length and width of the swimming pool are 20 ft and 12 ft respectively.
So, <u>the area of the swimming pool</u> ![=length*width= (20*12)ft^2= 240 ft^2](https://tex.z-dn.net/?f=%3Dlength%2Awidth%3D%20%2820%2A12%29ft%5E2%3D%20240%20ft%5E2)
Now a deck is being built around the pool and it has a uniform width of 6 ft.
So, the length of the pool including the deck
and the width of the pool including the deck ![=(12+6*2)ft=24 ft](https://tex.z-dn.net/?f=%3D%2812%2B6%2A2%29ft%3D24%20ft)
Thus, <u>the area of the pool including the deck</u> ![=(32*24)ft^2 = 768 ft^2](https://tex.z-dn.net/?f=%3D%2832%2A24%29ft%5E2%20%3D%20768%20ft%5E2)
So, the area of the deck only
By using the <em>area</em> formulae for triangles and rectangles and the concept of <em>surface</em> area of the <em>composite</em> figure is equal to 1108 square inches.
<h3>What is the surface area of the composite figure?</h3>
The <em>surface</em> area is the area of all faces of a solid. In this case, we must sum the areas of seven <em>rectangular</em> and two <em>triangular</em> faces to determine the <em>surface</em> area:
A = 2 · (0.5) · (12 in) · (9 in) + 2 · (11 in) · (20 in) + 2 · (5 in) · (20 in) + 2 · (5 in) · (12 in) + (12 in) · (20 in)
A = 1108 in²
By using the <em>area</em> formulae for triangles and rectangles and the concept of <em>surface</em> area of the <em>composite</em> figure is equal to 1108 square inches.

Answer:
Greater
Step-by-step explanation:
The answer goes up when there is decimals/fractions so you are basically multiplying. The answer to this would equal 308.
