"Area of a triangle"

Area of a Triangle

  • Formula: The area (A) of a triangle is calculated using the formula:

    A = \frac{1}{2} b h

    • Where:
    • bb = base length of the triangle
    • hh = corresponding height of the triangle (the height is perpendicular to the base)

  • Find the Area of the Triangle:

    • Given:
    • Base b=11extcmb = 11 ext{ cm}
    • Height h=9extcmh = 9 ext{ cm}

  • Calculation:

    • Substitute the values into the formula:

      A = \frac{1}{2} \times 11 \times 9
    • Simplifying:
    • First calculate the product: 11×9=9911 \times 9 = 99
    • Then calculate the area:

      A = \frac{1}{2} \times 99 = 49.5 ext{ cm}^2

  • Result:

    • The area of the triangle is 49.5extcm249.5 ext{ cm}^2.
    • Remember to include the units squared when reporting the area, as it represents a two-dimensional space.
