Curly used a shovel to dig his own swimming pool. He figured he needed a pool because digging it was hard work and he could use it to cool off after working on it all day. He also planned to build a rectangular concrete deck around the pool that would be 6 feet wide at all points. The pool is rectangular and measure 14 feet by 40 feet. What is the area of the deck?

Would it surprise you to discover that the area of deck will exceed the area of the pool?

No.

O.K. To solve this it will be easier if we make a diagram|dw:1378437166339:dw|

would you just add 6 to 14 and 20?

I think the best approach is to calculate the area of the largest rectangle which has a length of 40 + 6 + 6 = 52 and a width of 14 + 6 + 6 =26 feet. Do you understand why?

  • anonymous
why would you add them twice?
radar
  • radar
Because they are on each side making an increase of 12 feet in the linear dimensions of the pool.

Now you subtrace the small square which is 14 X 40 and you will have the area of the deck.

i have the answer, thanks.

52 X 26 = 1352 14 X 40 = 560 1352-560 = amswer

Do you agree?
anonymous
  • anonymous
no i dont i got 360.
radar
  • radar
560 is the area of the pool What did you multiply to get the 360?
anonymous
  • anonymous
i did 14x40 and got 560 then i added only one 6 to each umber and got 20x46 and got 920 then i subtracted 560 from 920 and got 360 for the area of the deck

thats what i did

You need to add the total distance and if you study the diagrams you will see that you must add 12 as there is 6 feet on each side for a total increase in length and width of 12. Please note that the deck goes all the way around the poo.
