The Singhs are putting a flagstone deck around their pool.

Question

The pool is rectangular.
Its dimensions are 10 m by 6 m.
The deck will surround the pool. It will have a width of 3 m.

What is the area of the deck?

Answer 1

Help me please I need this because without practice I won't pass my test!!!!!

Answer 2

the deck's area is the difference between the enclosed pool and just the pool.
The deck is on both sides, so its area is
(10+6)(6+6) - 10*6 = ____ m^2

Answer 3

Thanks but I need a certain formula bxh/2

Answer 4

If anyone can do that pleaseeee help

Answer 5

multiply 16 by 12 = 192 = area enclosed by outside of deck.
subtract 60 = area of pool itself
You get 132 m^2

b*h/2 is a triangle, nothing to do with a rectangular pool.

Answer 6

Thanks one more question: How much security fencing is required around the deck?

Answer 7

length of deck = 10 + 6 = 16
width = 6 + 6 = 12
so
2 * (12+16) = 56 meters

Answer 8

Of course you need a gate :)
