For easier notation lets use: Nn=x and Nd=y
x+y=22
5x+10y=135
Multiply the first equation by 5 to get
5x+5y=110
Now you can eliminate x by subtracting the first equation from the second
5x+10y-5x-5y=135-110
5y=25
y=5
x=17
The correct answer is A = 750 cm² because all you have to do is multiply the values of the parallelogram and you'll get 750 cm²:
30 cm*25 cm= 750 cm²
