Answer:
[tex]18x^3y[/tex]
Step-by-step explanation:
The area of a trapezium is [tex]\frac{a+b}{2}h[/tex] (where [tex]a,b[/tex] are the parallel sides and [tex]h[/tex] is the perpendicular height)
Area of trapezoid [tex]= \frac{4xy+8xy}{2}3x^2[/tex]
[tex]=6xy(3x^2)[/tex]
[tex]=18x^3y[/tex]
∴ The area of the trapezoid is [tex]18x^3y[/tex]
Hope this helps :)
