Explanation:
The formula for the area of a trapezoid is
, where
- a and b are the lengths of the top and bottom sides, and
- h is the height of the figure.
For this figure,
and
(the top and bottom sides), while
(the height).
If we suppose
is the area, plugging these values in, we get
All the lengths are in cm, so the area will be (x + 11) cm².
