When we’re asked to find the area of a triangle, what we’re looking for is the amount of space inside the sides of our triangle.

$A=2bh $

The formula is pretty straightforward, but correctly identifying the base and the height of the triangle can sometimes be tricky. That’s why we like to imagine triangles as mountains!

### Type of Triangle:

We can imagine the triangle as a mountain where the base is flat (⬌), and the height is a vertical line that connects the base to the peak (⬍).

## How to Find the Area of a Triangle

### Step 1. Identify the base and height of the triangle.

### Step 2. Multiply the base by the height.

### Step 3. Divide by 2.

We divide by 2 because the area of a right triangle is equal to ½ the area of a rectangle$(A=l×w=b×h)$made up of two right triangles with the same base and height.
