The unique property about the trapezoid is that it has only one pair of parallel sides. Those of the same colour are on the same parallel line of the trapezium. S tot total surface area.
S lat lateral surface area.
So the area of the trapezium is 39 cm 2. A top of parallel sides of trapezium. The area of a trapezium is computed with the following formula. The formula to calculate the area of a trapezium is.
