12×50=600
12×49=588
600-12=588
9 times 1.23 equals $11.07 so it cost $11.07
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
Substitute the value of the variable into the equation and simplify.
There for your answer is 10
