The plot of land is worth $18,000 and the tax on the land is $0.70 per $100. You would divide 18000 by 100 which is 180. Then you would multiply 180*0.70 which is $126.
According to PEMDAS, you always start solving an equation by answering what is inside of the parentheses first. (That's what the 'P' in PEMDAS stands for!)
It's reduction because the square becomes smaller, and that happens when reducing.
One side of the larger square is 4. The same side on the smaller square is 2. When it's reduction, the answer is less than 1. It will be 1/2 because 2 is 1/2 of 4.
