Question

Can anyone please help me?
This pool has a length of 20 feet and a width of 16 feet. The pool has a deck around it that is 6 feet wide. What is the area of the deck?

Answer 1

Have you done anything so far? What in particular are you stuck on?

Answer 2

I don´t know if I have to find the area of a rectangle or something else, but if I find the area of a rectangle, it isn´t one of my options (36)

Answer 3

I'm thinking... changing the width to 16 + 6 so then the length stays the same (so 20) then do what 16+6 equals x 20

Answer 4

440? That´s not one of my options though, these are
252 square feet

320 square feet

408 square feet

576 square feet

896 square feet

Answer 5

hmm..... idk know then, sorry

Answer 6

good luck though!

Answer 7

Hmm thank you anyway!

Answer 8

To find the area, we need to find the area of the larger rectangle (pool and deck) then subtract the area of the smaller rectangle (pool).

The pool is 20x16=320.
The deck is an extra 6 on each side, so we add 12 to each of those numbers: 32x28=896.
Area of deck=896-320=576.

Does that make sense?

Answer 9

Now it does make sense, I thought it was only the deck´s area on one side, thank you so much!

Answer 10

Do you mind helping me with another one?

Answer 11

@tom982

Answer 12

Sure no problem.

Answer 13

Ok so I have to find the area of this figure

Answer 14

But I don´t know what shape that is

Answer 15

It's not a regular shape, for these we have to break it down and work out the area of each part and add it together. If you look, they've split it into triangles and rectangles. Let's start with the top triangle, can you tell me its area?

Answer 16

ok... 2?

Answer 17

The top triangle has a base of 3cm and a height of 4cm, it's not 2.

Answer 18

6 then?

Answer 19

Yep. Now the rectangle below it and the bottom rectangle (or you could do it as one big one if you want).

Answer 20

hmm 36?

Answer 21

Yep. Now the two bottom triangles?

Answer 22

1 each?

Answer 23

so the answer is 44?
@tom982

Answer 24

Yep, perfect.

Answer 25

Thank you!

Answer 26

No problem at all.
