Title: Area of 2D shapes |
Grade: 8-a Lesson: S1-L5 |
Explanation: The best way to understand algebra is by looking at some examples. Take turns and read each example for easy understanding. |
Examples:
What’s the area of a 2D shape with a side length of 6m and a width of 4m?
Step 1a
|
|
The first 2D shape is a square. To calculate the area of a square, use the formula: \$36m^2\$. |
|
Explanation: Finding the area of a square is a simple task when the formula is used: \$A = 36m^2\$ (Area = side x side). |
|
Step 2a
|
|
The next 2D shape is a rectangle. To calculate the area of a rectangle, use the formula: \$24(m)^2\$ |
|
Explanation:
Finding the area of a rectangle is a simple task when the formula is used: \$A = 24m^2\$ |
|
Step 3a
|
|
The third 2D shape is a rhombus. To calculate the area of a rhombus use the formula: \$12m\$ |
|
Explanation: Finding the area of a rhombus is a simple task when the formula is used \$A = 12m\$ \$pq/2\$ |
