a = 12 cm

b = 14 cm

h = 8 cm.

Compute the area. How many cm2?

  • Geometry -

    You can use Heron's formula, which calculates the area of a triangle from the lengths of the three sides.

    Let a,b,c=lengths of the three sides
    s=(a+b+c)/2
    Area of triangle
    =sqrt(s(s-a)(s-b)(s-c))

    Post your answer for a check if you wish.

  • correction -

    I believe the figure is a trapezoid. I have misread it as a triangle (with given sides a, b and c).

    The area of a trapezoid (trapezium) is
    (a+b)h/2
    =(12+14)*8/2
    =104
