Answer 1

Answer:

The area of figure is 84 square units

Step-by-step explanation:

See the attached figure for solution.

Answer 2

For this case, the total area of the polygon is given by;

$A_ {t} = A_ {1} + A_ {2}\\A_ {1} = 12 * 6\\A_ {1} = 72 \ square \ units$

On the other hand we have to:

$A_ {2} = (10-6) * (12-9)\\A _{2} = 4 * 3\\A_ {2} = 12 \ square \ units$

So, finally we have:

$A_ {t} = A_ {1} + A_ {2}\\A_ {t} = 72 \ square \ units \ + \ 12 \ square \ units\\A_ {t} = 84 \ square \ units$
