Answer:
First one: 37.5
Second one: 108 
Step-by-step explanation:
For the first one: 
the figure shown is a triangle 
The area of a triangle can be calculated using this formula 
 where b = base length and h = height
 where b = base length and h = height 
The triangle shown has a height of 7.5 and a base length of 10 
Using this information we plug in the values into the formula. 

Hence the area of the figure is 37.5 square units
For the second one. 
The figure shown is a parallelogram with a height of 9 and a base length of 12 
The area of a parallelogram can simply be calculated by multiplying the base length by the height 
So area = 9 * 12 
9 * 12 = 108
Hence the area of the figure is 108 square units
