Study Notes
Area of a Triangle
- Area can be calculated using the formula: Area = (base × height) / 2
- Example: For a triangle with a base of 17 inches and height of 8 inches, the area is 68 sq.inches.
Definition of Area
- Area refers to the number of square units contained within the interior of a polygon.
Sample Calculations
- An obtuse triangle with a base of 16 units and height of 8 units has an area of 64 sq.units.
- A triangle with a base of 17 units and height of 4 units has an area of 34 sq.units.
- If a triangle has an area of 24 sq.inches and a base of 6 inches, the height is calculated to be 8 inches.
- An acute triangle with a base of 12 inches and height of 6 inches has an area of 36 sq.inches.
- An obtuse triangle with a base of 9 units and height of 2 units has an area of 9 sq.units.
- An obtuse triangle with a base of 15 inches and height of 13 inches has an area of 97.5 sq.inches.
Area of a Rectangle
- Area of a rectangle can be calculated as Area = base × height.
- Example: A rectangle with a base of 17 units and height of 8 units has an area of 136 sq.units.
- A rectangle with a base of 22 units and height of 3 units has an area of 66 sq.units.
