The height and bases of these two trapezoids are the same, so the trapezoids are congruent. Use the formula for area of a trapezoid to find the area of one of the trapezoids, and then double that to get the area of the entire figure.
Formula for area of a trapezoid:
A = (a + b)/2 * h, where a and b are the bases and h is the height.
The bases and height are given as follows:
a = 16
b = 24
h = 12
Plug these values into the formula accordingly and solve.
A = (a + b)/2 * h
A = (16 + 24)/2 * 12
A = 40/2 * 12
A = 20 * 12
A = 240
The area of one trapezoid is 240 units². Remember, to get the total area, this must be doubled.
240 * 2 = 480
Answer:
b. 480 units²
