h=9
A=((a+b)/2)h
234=((32+20)/2)h
234=(52/2)h
234=26h
9=h
Answer: 88
Step-by-step explanation: To find 55% of 160, first write 55% as a decimal by moving the decimal point two places to the left to get .55.
Next, the word "of" means multiply, so we have (.55) x (160).
(.55) (160) = 88
Therefore, 55% of 160 is 88.
