What’s the area of a 2D shape with a side length of 6m and a width of 4m?
Step: 1 |
|
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 = 36 m^2 ("Area" = "side" \times "side")\$. |
|
Step: 2 |
|
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 = 24 m^2\$ (Area = length \$\times\$ width). |
