Objective : Learn to find the area of a triangle.

2. Area of Triangles
To find the area of a triangle, you have to multiply the base by the height, and then divide by 2.
Area = base × height 2
or A = b × h

3. Examples: Example 1: Find the area of the triangle:
Steps to finding the area of a triangle:
Copy the formula.
Substitute the numbers in the formula.
3. Multiply the base and the height.
4. Divide your answer by 2.
Write the answer with the unit2 .
A = b × h 2
A = 4cm × 6cm
A = 24 cm2
A = 12 cm2
