The area of the following trapezoid is 210mm².
How to calculate the area of a trapezoid?
The area of a trapezoid can be calculated if the length of its parallel sides and the perpendicular distance (height) between them is given. The formula for the area of a trapezoid is expressed as,
Area = {(a + b) × h} / 2
Where a and b are the parallel sides and h is the height in the figure below.
In the given question we have, a = 14 mm , b = 28 mm and h = 10 mm.
So, by using the formula for finding the area of a trapezoid,
Area = {(14 + 28) × 10} / 2
= {42 × 10 } / 2
= 420 / 2
= 210
The unit of the area is mm².
Therefore, the area of the following trapezoid is 210 mm².
