Grade: 1400-a Lesson: S3-L5 |
Explanation: Hello Students, time to learn examples. Let us take turns and read each example. Explain each step. Pay special attention to steps and pictures and communicate in your own words. |
Examples:
What is 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: Area = side x side. |
|
Explanation: Finding the area of a square is a simple task when the formula is used: \$A = 36m^2 \$. |
|
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\$ \$"Area" = "length" times "width"\$. |
|
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\$ |
