So you know that altogether the ratio adds up to 22. just do 88/22 to find what 1 is. then just multiply 88/22=4 5=5x4 which is 20 7=7x4 which is 28 10=10x4 which is 40 the answer is 20 cm, 28 cm, and 40 cm.
Base times height divided by 2 is the area. So 14 times 22 is 308 and divided by 2 is 154 so that is your answer. I hope this helps. Could I possibly get brainliest?
