Answer:
44
step-by-step explanation:
Formula
1/2*h*(sum of parallel sides(b1+b2))
Your scale on both axes are 2cm to 2units therefore the parameters are as follows
h=4
b1=9
b2=13
[tex] \frac{1}{2} \times 4 \times (9 + 3)[/tex]
[tex] = \frac{1 \times 4 \times 22}{2} [/tex]
[tex] = \frac{88}{2} [/tex]
=44
