Answer:
44
Step-by-step explanation:
Formula
[tex] \frac{1}{2} \times h \times (sum \: of \: parallel \: sides(b1 + b2))[/tex]
Your scale is 2cm to 2units therefore the parameters are as follows
h=4
b1=9
b2=13
[tex] \frac{1}{2} \times 4 \times (9 + 13)[/tex]
[tex] \frac{1}{2} \times 4 \times 22[/tex]
[tex] \frac{1}{2} \times 88[/tex]
[tex] \frac{88}{2} \\ = 44[/tex]
