We can use the following equation to find the area of a trapezoid:
[tex]A=\dfrac{a+b}{2}\times h[/tex]
We're given:
Plug these values into the equation:
[tex]A=\dfrac{a+b}{2}\times h\\\\A=\dfrac{3+10}{2}\times 24\\\\A=\dfrac{13}{2}\times 24\\\\A=13\times 12\\\\A=156[/tex]
Therefore, the area of the trapezoid is 156 units squared.
