Answer: 450 is your answer
It is 255 cm^2
This is a very basic area problem. You should try refreshing on some of your multiplication and addition skills. Try reading patterns, maybe. Also learning geometric proofs is VITAL.
Answer:
b and d
Step-by-step explanation:
parallel means go in the exact same direction and if they never ended, they would never touch
If the 2 given points are endpoints, then we're in business. The formula for the midpoint is
