Answer:
B. 13.5 in^2
Step-by-step explanation:
Use the formula [tex]\frac{a+b}{2} h[/tex].
Step 1- Substitute into the formula.
[tex]\frac{a+b}{2} h[/tex] = [tex]\frac{4+5}{2} 3[/tex]
Step 2- Add to simplify
[tex]\frac{4+5}{2} 3[/tex] = [tex]\frac{9}{2}3[/tex]
Step 3- Divide
9/2= 4.5
Step 4- Multiply
4.5× 3= 13.5
