Answer: 
Step-by-step explanation:
Area of parallelogram = Base x height
If two parallelograms are similar, then their corresponding sides are proportional.
That means, 

Hence, 
Simply divide $25,200 by 5

$5,400 was spent on housing

Answer:
31.5 cm²
Step-by-step explanation:
Calculate area of a triangle with this formula:
Area =
base * height
Substitute in known values
Area =
7 * 9
Multiply 7 by 1/2
Area = 3.5 * 9
Multiply
Area = 31.5 cm²
Hope this helps :)
