Question

The perimeter of triangle B is 2.5 times greater than the perimeter of triangle A.The area of triangle B is how many times greater than the area of triangle A?

Answer 1

Triangle A and triangle B are similar since the scale factor of the length is 2.5

The scale factor of area is the square of scale factor of the length;
`2.5^(2) =6.25`

Hence, the area of triangle B is 6.25 time greater than triangle A
