Title: Area of Triangle |
Grade: 6-a Lesson: S1-L8 |
Explanation: The best way to understand geometry is by looking at some examples. Take turns and read each example for easy understanding. |
Examples:
Find the area of a triangle having base is 8 cm and height is 12 cm.
Step 1a
|
|
The base(b) and height(h) of a triangle (b) are 8 cm and 12 cm. |
. |
Explanation: Calculate the area of a triangle using the formula A = \$1/2\$ x base x height.For example, if the base is 18 and the height is 12, then the area is 54 |
|
Step 1b
|
|
Now,calculate the area of Triangle is A = \$1/2 \times b \times h\$ A = \$1/2 \times 18 \times 12\$ After simplification, the value we get, A = \$108/2\$ = 54 |
|
Explanation: Calculate the area of a triangle using the formula : A = \$1/2\$ x base x height. In this example, the base is 18 and the height is 12,then the area is 54. |
|
Step 1c
|
|
Therefore, the area of the triangle is 54 sq.cm |
|
Explanation: The area of the triangle is 54 square centimeters. |
