Final answer:
The area of a trapezoid is calculated using the formula A = 1/2 * (base1 + base2) * height. The answer is the result of substituting the values of the bases and height into the formula.
Step-by-step explanation:
The area of a trapezoid can be calculated using the formula:
A = 1/2 imes (base_1 + base_2) imes height
where base_1 and base_2 are the lengths of the parallel sides of the trapezoid, and height is the perpendicular distance between the parallel sides.
For example, if the lengths of base_1 and base_2 are 5 units and 7 units respectively, and the height is 6 units, the area of the trapezoid would be:
A = 1/2 imes (5 + 7) imes 6 = 1/2 imes 12 imes 6 = 36
