Answer:
66in²
Step-by-step explanation:
If we assume the rectangle is made out of two identical trapezoids, as the question suggests, well then we know that the length of the triangle is equal to the sum of the length of the top and the bottom of the trapezoid:
Length(rectangle)=3+8=11
Width(rectangle)=6
Area(Rectangle)=length*width=11*6=66in²
