Answer:
the area of this trapezoid= 81 square inches
Step-by-step explanation:
To find area of trapezoid , we use formula
[tex]Area = \frac{a+b}{2} * h[/tex]
Where a,b are the base of the trapezoid
h is the height of the trapezoid
Here a= 3 in
b = 15 in
h = 9 in
Plug in all the values in the formula
[tex]Area = \frac{a+b}{2} * h[/tex]
[tex]Area = \frac{3+15}{2} * 9[/tex]
[tex]Area = \frac{18}{2} * 9[/tex]
Area = 9 * 9 = 81
the area of this trapezoid= 81 square inches
