What is the area of the yellow triangle?

lesantik [10]

I can't see pictures, but to find the area of a triangle, you multiply the dimensions, as you would a rectangle, but divide the area by 2.

For example, the dimensions of a triangle are 4 and 6.

Multiply the two.

4x6=24.

But don't stop there. Divide 24 by 2.

24/2=12.

So the area of the example triangle is 12.
