Answer:
See below.
Step-by-step explanation:
If it is a regular polygon then you can look up the formula or break it into shapes you do know the formula. 
If it is irregular or a composite figure, break it into regular polygons which do have formulas to find the area. Here is an example:
Example:
Find the area of the composite figure by splitting the figure into two shapes - two rectangles.
One rectangle is 2 x 9 = 18.
The other rectangle is 2 x 4 = 8.
Together the area is 18 + 8 = 26.

Answer:
6·<u>¹₂</u>            6¹/₂
Step-by-step explanation:
by dividing 13 by 2, we get the quotient 6, remainder 1 and divisor as 2.
as we know, to write a mixed fraction, we follow Q^R/D, so we get 6¹/₂.
