Answer:
The perimeter of Chen's office is 46.6 feet.
Step-by-step explanation:
Since the perimeter P = 2l + 2w where l = length of Chen's office and w = width of Chen's office.
Now, since length of Chen's office = l = 15.5 feet and width of Chen's office = w = 7.8 feet, we substitute these values into the equation for the perimeter.
Substituting these values of length and width, we have
P = 2l + 2w
P = 2(15.5) + 2(7.8)
P = 31 + 15.6
P = 46.6 feet
So, the perimeter of Chen's office is 46.6 feet.
