Answer:
18 square centimeters
Step-by-step explanation:
Notice that if e is the midpoint of the side CB, and angle 
, then this rectangle is in fact two squares of side 3 cm put together. therefore, side CD has a length of 6 cm, and as a result, the area of the figure is given by the product base times height = 6 x 3 = 18 
10% of 30 is 3, which means it rained 3 days.
30-3 = 27 days NO rain
Multiply -2 by 3z and -4y
-6z + 8y -z
subtract z from -6z
-7z + 8y should be your answer
