The area of triangle B is 64 times greater than the area of triangle A.The perimeter of triangle B is how many times greater than the perimeter of triangle A?

how many times greater than the perimeter of triangle A?


A. 8 times greater
B.64 times greater
C.128 times greater
D.256 times greater

  • Update Math Question -

    area=sqrt(s(s-a)(s-b)(s-c)) where s is the semi perimeter.

    so area=f(sqrt s^4) or f(s^2)

    so if area increases by 64, s must have increased by 8
