area of a trapezoid lesson plan | 1.55 | 0.3 | 2765 | 34 |

You can notice that for a trapezoid with a = b (and hence c = d = h), the formula gets simplified to A = a * h, which is exactly the formula for the area of a rectangle. How to find the perimeter of a trapezoid? You can also use the area of a trapezoid calculator to find the perimeter of this geometrical shape.

The area of a trapezoid is the number of unit squares that can be fit into it and it is measured in square units (like cm 2, m 2, in 2, etc). For example, if 15 unit squares each of length 1 cm can be fit inside a trapezoid, then its area is 15 cm 2 .

It is mathematically expressed as A = ½ (a + b) h, where 'a' and 'b' are the bases (parallel sides) and 'h' is the perpendicular height. It is represented in terms of square units. How to Find the Area of a Trapezoid?

The parallelogram formed by the two congruent trapezoids has a base b 1 + b 2 and height h. Therefore, the area of this parallelogram is: A = (b 1 + b 2 )h. Since the parallelogram is made up of two congruent trapezoids, halving the above formula gives us the formula for the area of one of the trapezoids:
