what is the area of the trapazoid

7cm
8cm
4cm

The area of a trapezoid is calculated using the formula:

Area = (a + b) * h / 2
where a and b are the lengths of the parallel sides of the trapezoid and h is the height.

In this case, a = 7cm, b = 8cm, and h = 4cm.
Plugging these values into the formula:
Area = (7 + 8) * 4 / 2
Area = 15 * 4 / 2
Area = 60 / 2
Area = 30 square centimeters.

Therefore, the area of the trapezoid is 30 square centimeters.
