You need to lay communications cable around the perimeter of three offices, each 8' by 10'. How much cable do you need?

To calculate the amount of cable needed to lay around the perimeter of three offices, we can follow these steps:

Step 1: Calculate the perimeter of one office
The perimeter of a rectangle is given by the formula:
Perimeter = 2(length + width)
For an 8' by 10' office:
Perimeter = 2(8 + 10)
Perimeter = 2(18)
Perimeter = 36 feet

Step 2: Calculate the perimeter of three offices
Since you have three offices with the same dimensions, you need to multiply the perimeter of one office by 3:
Total Perimeter = 36 feet * 3 offices
Total Perimeter = 108 feet

Therefore, you would need 108 feet of cable to lay around the perimeter of three offices.

To find the length of cable needed to lay around the perimeter of three offices, you need to calculate the total perimeter of all three offices combined.

1. Start by calculating the perimeter of a single office. Since each office has dimensions of 8' by 10', you can find the perimeter using the formula:

Perimeter = 2 * (Length + Width)

For the first office, the perimeter would be:
Perimeter1 = 2 * (8 + 10) = 36 feet

2. Since you have three offices, multiply the perimeter of a single office by 3 to find the total perimeter:

Total Perimeter = Perimeter1 * 3 = 36 * 3 = 108 feet

Therefore, you would need 108 feet of cable to lay around the perimeter of the three offices.

P = 3(2L + 2W)

P = 6L + 6W

P = (6 * 10) + (6 * 8)

P = 60 + 48

P = ?
