To find the area of a rectangle, you multiply its length by its width. The formula is:
Area=Length×Width\text{Area}=\text{Length}\times \text{Width}Area=Length×Width
Steps to Calculate Area of a Rectangle:
- Measure or note the length and width of the rectangle.
- Multiply these two values.
- Express the result in square units (such as cm², m², etc.).
Example:
If a rectangle has a length of 15 units and a width of 4 units, its area is:
15×4=60 square units15\times 4=60\text{ square units}15×4=60 square units
This means the rectangle covers an area of 60 square units
Additional Notes:
- If you know the diagonal and one side, you can use the Pythagorean theorem to find the missing side and then calculate the area.
- If you know the perimeter and one side, you can find the other side using the perimeter formula P=2×(L+W)P=2\times (L+W)P=2×(L+W), then calculate the area.
But the simplest and most direct method is always multiplying length by width
