Question

find the area of trapezoid wxyz. round your answer to the nearest tenth if necessary.
(image of trapezoid wxyz with sides: xy = 12.2 in, yz = 10 in, zw = 12.6 in, wx = 16 in, and a height of 12 in between the two parallel sides)

Explanation:

Step1: Identify trapezoid parts

A trapezoid has 2 parallel sides (bases) and height (distance between them). Here, the height is 12 in, bases are 10 in and 16 in.

Step2: Apply area formula

Area = $\frac{1}{2}×(base_1 + base_2)×height = \frac{1}{2}×(10 + 16)×12$

Step3: Calculate

$\frac{1}{2}×26×12 = 13×12 = 156$? Wait, no—wait, check bases again: Wait, trapezoid WXYZ: sides XY=12.2, YZ=10, ZW=12.6, WX=16. The height is 12 (perpendicular distance). The two parallel sides are YZ (10) and WX (16). So area is $\frac{1}{2}×(10+16)×12 = 156$? Wait, no, wait the problem says round to nearest tenth but 156 is whole number. Wait, no—wait, maybe I misread: no, the formula is correct. Wait, 10+16=26, half is 13, 13×12=156. So answer is 156.0? Wait, original calculation: yes.
Wait, correction: $\frac{1}{2}×(10+16)×12 = 156$. So final answer is 156.0.

Wait, I think I made a typo earlier. Correct answer is 156.0.

Step1: Confirm trapezoid parameters

Bases: 10 in and 16 in; height:12 in.

Step2: Use area formula

Area = $\frac{1}{2}(b_1+b_2)h = \frac{1}{2}(10+16)×12$

Step3: Compute result

$\frac{1}{2}×26×12 = 156.0$
