Can someone please help me.

Answer:
[tex]\displaystyle \boxed{12\frac{1}{2}}\:units^2[/tex]
Step-by-step explanation:
[tex]\displaystyle \frac{[b_2 + b_1]h}{2} = A\:or\:\frac{1}{2}h[b_2 + b_1] = A[/tex]
Plugging these dimensions into either formula will arrive at your answer of [tex]\displaystyle 12\frac{1}{2}\:square\:units.[/tex]
