Answer:
36 sq. units
Step-by-step explanation:
Area of any Trapezoid can be found by the formula Area=[tex]\frac{1}{2} (sum of length of bases)xheight[/tex]
The base angles are given as 45 degrees so we have a 45 45 90 triangle .In 45 45 90 triangle legs are same so height = 3.
Area of trapezoid =[tex]\frac{1}{2} (9+15).3[/tex]
=[tex]\frac{1}{2} (24).3=36square units.[/tex]
