a 12 ft by 16 ft rectangular swimming pool has a 3 ft wide no slip serface arond it what is th outer perremeter around it
the 3' border on each side increases each dimension by 6. So, the outside dimensions are
18 by 22
Now you can figure the perimeter, right?
To find the outer perimeter of the swimming pool, we need to calculate the overall dimensions of the pool including the no-slip surface around it.
The original dimensions of the pool are 12 ft by 16 ft. Since the no-slip surface extends 3 ft on each side, we need to add 3 ft to each dimension.
The new dimensions of the pool, including the no-slip surface, are:
Length = 12 ft + 3 ft + 3 ft = 18 ft
Width = 16 ft + 3 ft + 3 ft = 22 ft
Now, we can calculate the outer perimeter by adding up all the sides of the pool:
Perimeter = 2(Length + Width)
Perimeter = 2(18 ft + 22 ft)
Perimeter = 2(40 ft)
Perimeter = 80 ft
Therefore, the outer perimeter around the swimming pool, including the 3 ft wide no-slip surface, is 80 feet.
To find the outer perimeter of the rectangular swimming pool, we need to take into account the dimensions of the pool itself as well as the additional 3 ft wide no-slip surface surrounding it.
The length of the pool is given as 12 ft, and the width is given as 16 ft. To find the total length including the no-slip surface, we add twice the width of the no-slip surface (3 ft) to the length of the pool.
So, the total length is 12 ft + 3 ft (no-slip surface on one side) + 3 ft (no-slip surface on the other side), which gives us 18 ft.
Similarly, for the width of the pool, we add twice the width of the no-slip surface to the width of the pool. Therefore, the total width is 16 ft + 3 ft + 3 ft, which equals 22 ft.
Now that we have the total length and width, we can calculate the outer perimeter by summing the lengths of all four sides.
The two lengths (18 ft) are opposite sides and the two widths (22 ft) are the adjacent sides.
Adding all four sides together gives us: 18 ft + 18 ft + 22 ft + 22 ft = 80 ft.
Therefore, the outer perimeter around the rectangular swimming pool, including the 3 ft wide no-slip surface, is 80 ft.
