Answer:
336 units²
Explanation:
Consider the figure as two triangles (one on top and one on bottom, divided by the line you drew), find the area of each triangle, and then add them together to find the total area of the figure.
Note that the formula for the area of a triangle is: 0.5*base*height.
Area of top triangle = 0.5*24*10=120 units²
Area of bottom triangle = 0.5*24*18 = 216units²
Therefore the total area of the figure = 120 +216 = 336 units²
