I want to put a 3ft wide walk around a 10ft by 15 ft pool. What is the perimeter around the figure including the path?
To find the perimeter of the figure including the walkway, you would need to calculate the total length around both the pool and the walkway. Here's how you can do it step by step:
Step 1: Calculate the dimensions of the pool plus the walkway. Since the walkway is 3 feet wide, you need to add 3 feet to each side of the pool.
Pool with Walkway:
Width: 10 ft + 2(3 ft) = 10 ft + 6 ft = 16 ft
Length: 15 ft + 2(3 ft) = 15 ft + 6 ft = 21 ft
Step 2: Find the perimeter of the figure. The perimeter is the sum of all the sides of the figure.
Perimeter = 2(Width + Length)
Perimeter = 2(16 ft + 21 ft)
Perimeter = 2(37 ft)
Perimeter = 74 ft
Therefore, the perimeter around the figure, including the walkway, is 74 feet.
