what I done was subtract 120 from 144 which will leave 24 then I find the percentage.
This makes it 3/24. When you divide the fraction out, you get 0.125. To turn that into a percentage, you simply multiply by 100. 0.125*100=12.5% you can check this by taking 12.5% of 24, which will give you an answer of 3
Both A and C is true. However, even though a rectangle can be a parallelogram, a parallelogram is a quadrilateral, so the answer is A. I hope this helps!
