The length and width of a rectangular projector screen in a small theatre is 200% more than the length and width of a television screen in the same room. How much bigger is the area of the screen than that of the television? Give your answer as a percentage.

Answer 1

200% more means three times as large

the length and width of the projector screen are three times the length and width of the television screen

this means the area of the larger screen is nine times the area of the smaller

nine times means 800% more
