Sally wants to build a fence around her pool. The pool is 26 feet long and 21 feet wide. The fence is to be 15 feet from the edge of the pool.

What are the dimensions of the area surrounding the pool?

How many feet of fencing will Sally need?

A. 41 ft by 36 ft; 77 ft**
B. 41 ft by 36 ft; 154 ft
C. 56 ft by 51 ft; 214 ft
D. 56 ft by 51 ft; 107 ft

I am not sure on this, can you tell me if I am right, and how to do it?

c is correct.

Ok is it D?

I wasn't guessing

I added 26 and 30 to get 56
then i added 21 and 30 to get 51
then I added them together to get 107
so, is it d?

yes it is d

Thanks.

wait it is not d it is c

Oh, at my school D was correct

wow gg

I'm confused where do you guys get 30 from? Also, how did she/he get 107 bcs I got 102?

nevermind

Did you know?

Did you know that when building a fence around a pool, it's important to calculate the dimensions of the surrounding area? In this case, the pool is 26 feet long and 21 feet wide, with the fence placed 15 feet from the edge of the pool. To find the dimensions of the area surrounding the pool, we add up the lengths and widths of the pool, as well as the distance from the edge: (26 + 15) feet by (21 + 15) feet. This gives us an area of 41 ft by 36 ft. Now, to determine how many feet of fencing Sally will need, we calculate the perimeter of the area surrounding the pool. The formula for finding perimeter is 2 x (length + width). In this case, the perimeter would be 2 x (41 + 36), which equals 154 ft. Therefore, Sally will need 154 feet of fencing to build the fence around the pool. So, the correct answer is option B: 41 ft by 36 ft; 154 ft.
