The length of Chen’s office is 15.5 feet and the width is 7.8 feet. Use the formula p=2l + 2w to find the perimeter of the offic
solniwko [45]

Answer:

P = 46.6 feet

Step-by-step explanation:

P = 2L + 2W, where P is perimeter, L is length, and W is width.

2 x Length (L) = 2 x 15.5 feet = 31 feet;

2 x Width (W) = 2 x 7.8 feet = 15.6 feet.

Add both length and width together:

2L + 2W = 30.1 + 15.6 = 46.6 feet.

The perimeter (P) = 46.6 feet.
