The perimeter of a rectangular office is 30 feet. the width of the office is 5 feet. what is the length of the office?
a. 5ft
b. 10ft
c. 70ft.
d. 150ft

Answr:

Choice B is correct answer.

Step-by-step explanation:

From question statement , we observe that

Perimeter and width of the office is given.

Perimeter = 30 feet and width = 5 feet

We use the formula of perimeter to find the length of office.

P = 2l + 2w

putting the values of perimeter and width in the formula, we get

30 = 2l + 2(5)

30 =2l +10

30-10 = 2l

20 = 2l

l = 10 feet

hence, the length of office is 10 feet.
