Question

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

Answer 1

The length of the office is 36.4 ft

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

⇒
`(82)/(100)   * 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
