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.
1. 41 ft by 36 ft; 77 ft
2. 41 ft by 36 ft; 154 ft
3. 56 ft by 51 ft; 214 ft
4. 56 ft by 51 ft; 107 ft
I'll be happy to help
Your Answer Is D.
Hope This Helps.
To determine the dimensions of the fence, we need to add 30 feet to both the length and width of the pool (15 feet on each side) to account for the desired distance between the fence and the pool's edge.
Given that the pool is 26 feet long and 21 feet wide, we add 30 feet to each dimension:
Length of the pool with the fence: 26 ft + 30 ft = 56 ft
Width of the pool with the fence: 21 ft + 30 ft = 51 ft
Therefore, the dimensions of the fence are 56 feet by 51 feet.
Next, we need to calculate the total amount of fencing required. Since we want to surround the pool entirely, we need to calculate the perimeter of the rectangular shape formed by the fence.
Perimeter of a rectangle = 2 * (length + width)
Substituting the values:
Perimeter of the fence = 2 * (56 ft + 51 ft) = 2 * 107 ft = 214 ft
Hence, the answer is option 3. 56 ft by 51 ft; 214 ft.
But there was no question !!!
If you want the perimeter of the fence, then
the fence would be 56 ft by 51 ft, for a perimeter of 2(56+51) ft or 214 ft.
which looks like choice #3
