Question

A classroom is 20 feet long. The office is 82% longer than the classroom. How long is the office?

Answer 1

Answer:

The length of the office is  36.4 ft

Step-by-step explanation:

The length of the classroom  =  20 ft long

The length of the office =  20 ft + 82% of the classroom length

Now, 82 % of classroom length  =  82 % of 20 ft

⇒ $\frac{82}{100} \times 20 = 16.4$

or, 82% of 20 ft = 16.4 ft

⇒The length of the office  = 20 ft + 16.4 ft  = 36.4 ft

Hence, the length of the office =  36.4 ft
