Question

The height of a television screen is 75% of its width. The screen is 20 inches wide.

What is the area of the television screen?

By percent, how does this area compare to the area of a 20-inch by 20-inch screen?

Answer 1

Area = height *width

Area = (.75)(20)*20 = 15*20 = 300

Area of 20 by 20 screen = 20*20 = 400

300/400 = 3/4 = 0.75 = 75%
