Area of triangles
The area of triangles can be found by using the following formula. As you can see, to find the area, just multiply the base by the height and divide the result by 2.
The figure below illustrates what base and height are
The red line represents the length of the base (call it b if you want) and the blue line represents the length of the height.
To get the area, just multiply the value of the base by the value of the height and divide the result by 2.
Example #1
Find the area for the following figure:
The area is 18 square inches or 18 inches
^{2}
Example #2
Find the area for the following figure:
The area is equal to (4 ×3)/2 or 12/2
The area is 6 inches
^{2}
Example #3
Find the area for the following figure:
The area is (5 × 6)/2 = 30/2
The area is 15 inches
^{2}
