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?

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;

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

The final answer is 3x3+6x2+8x+24+47x−2mark me brainliest
