A painter has painted a picture on a piece of canvas that measures 10 ֳ— 14 inches. In order to accommodate a frame, he has left an unpainted margin of 1 inch all the way around. What part of the canvas has been painted?
Suggested Answer:A🗳️
The area of the entire piece of canvas = 10 inches ֳ— 14 inches = 140 square inches. The portion painted on equals 8 inches ֳ— 12 inches = 112 square inches. (This is determined by subtracting 1 inch from the length of each side to account for the margin.) The portion used for painting can be expressed as a fraction: 112ג„ 140. Reduce this fraction (divide 112 by 140) to determine that 80% of the canvas is covered with paint.
