Question

The perimeter of triangle B is 6 times greater than the perimeter of

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

A. 36 times greater
B. 6 times greater
C. 3 times greater
D. 1.5 times greater

Answer 1

This is the concept of scale factors, to answer the question we proceed as follows;
linear scale factor=[Perimeter of B]/[Perimeter of A]=6
also:
Area scale factor=[linear scale factor]^2
but;
linear scale factor=6
hence;
Area scale factor=6^2=36
therefore we conclude that the area of triangle B is 36 time than that of triangle A. The answer is:
A] 36 times greater.
