5 Must Know Facts For Your Next Test
- The formula for the area of a rectangle is length multiplied by width (A = l ร w).
- To find the area of a triangle, use the formula: A = 1/2 ร base ร height.
- The area of a circle is calculated using A = ฯrยฒ, where r is the radius.
- For irregular shapes, the area can be approximated by dividing them into regular shapes and summing their areas.
- Area conversion between different units (e.g., square meters to square feet) involves squaring the linear conversion factor.
