A right triangle has an area of 13m squared. the dimensions of the triangle are increased by a scale factor of 3 what is the ares of the new triangle?

So, a right triangle with an area of 13m squared would have legs of 13 and 2.

Scale factors is simply a number that multiplies the dimensions of a shape.

So since, in this case the scale factor is three, then the dimensions of the new shape will be three times larger than the original.

If I'm correct then

13*3=39

2*3=6

A = 1/2bh

A=117 m squared

Now, the thing here is since it's squared, we must square our scale factor as well. 3^2=9 ... Does 13*9=117? Yes, so therefore we're correct!

Use this formula next time!

y=cx

New # = scale factor * original dimension
