Question
A rectangular school banner has a length of 44 inches, a perimeter of 156 inches, and an area of 1496 square inches. The cheerleaders make signs similar to the banner. The length of a sign is 11 inches. What is its perimeter and its area?
- Perimeter = 39 inches, Area = 93.5 square inches
- Perimeter = 93.5 inches, Area = 39 square inches
- Perimeter = 34 inches, Area = 105.6 square inches
- Perimeter = 105.6 inches, Area = 34 square inches
Hint:
perimeter = lengths of corresponding side
areas = square of lengths of corresponding sides
Finding the ratio of perimeter and area
The correct answer is: Perimeter = 39 inches, Area = 93.5 square inches
Ratio of perimeters = Ratio of lengths of corresponding sides
= P = 44 inches
Ratio of areas = Ratio of square of lengths of corresponding sides
A = 94 inches
A = 94 inches
