A^2+b^2=c^2 (Pythagoran theorem)

-> 30^2 + length^2 = 78^2
-> length = √6084-900 = <span>√5184 = 72 ft

=> area = length x width = 72 x 30 = 2160 ft^2</span>

A classroom is 20 feet long. The office is 82% longer than the classroom. How long is the office?
enyata [817]

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
