Question

The area of a triangle A is 15 square units. The area of triangle B is 60 square units. A) What scale factor was used to get from triangle A to triangle B? Scale Factor = _________b) Using the same triangle A that has an area of 15 square units as the original, what would be the area be of a scaled copy that was drawn using a scale factor of 5? Area = ____square units

Answer 1

Scale Factor of 4, and

At a scale factor of 5, the new area = 75 units^2

Explanation:

Triangle A area = 15 units^2

Triangle B area = 60 units^2

Scale Factor = (60 units^2)/(15 units^2) = 4

At a scale factor of 5, the new area would be 5*(15 units^2) = 75 units^2
