The tent has a square base. 18. A rectangular pool that is fifteen feet wide and twenty feet long is surrounded by a
deck that is four feet wide. What is the area of the surface of the deck?

160 sq. feet

Step-by-step explanation:

Given: Dimension of rectangular pool :

Length =  20 feet

width = 15 feet

Area of rectangular pool = length x width

= 20 feet  × 15 feet

= 300 sq. feet

Now, Length of deck = 20 feet + 4  feet+ 4   feet           (For both sides)

= 28 feet

width of deck = 15 feet + 4  feet+ 4   feet  = 23 feet

Area of deck including pool = 20 feet  ×  23 feet

= 460 sq. feet

Area of deck = (Area of deck including pool ) -(Area of rectangular pool)

= 460 - 300 sq. feet

= 160 sq. feet

Hence, the area of the surface of the deck= 160 sq. feet
