What is the area of Triangle PQR on the grid?

Don't let the fact that the triangle is upside down throw you off. Say X is where you drop a perpendicular from Q to PR. If we set PR as the base, and XQ as the height, after that it's straightforward. $$B \cdot H \cdot 1/2 = 4 \cdot 3 \cdot 1/2 = 6$$ .

Hope this helps!

To find the area of a triangle you must use the formula: B*H* $$\frac{1}{2}$$

So we must fid the base and height:

B: 4

H: 3

Multiply them together

4 * 3 = 12

Then multiply it by $$\frac{1}{2}$$

$$12 * \frac{1}{2} = 6$$

The Area of Triangle PQR is 6

Hope this helps ;P

don't forget the units squared, you have to add that!

The area is    6 units squared
