Anyone know how to do either of these?

Parallelegram area= b×h
base 1: 36
height 1: 24
base 2: 27
height 2: ?
The area does not change even if you are using different bases and heights because you are still solving for the same parallelegram as long as you use the right measurements with eachother, so to find h you can set the areas equal to eachother
36×24=27h
864=27h
÷27 both sides
h=32

corresponding means they belong together
base 1: 19.5
height 1: 8.1
base 2: 40.5
height 2: ?
19.5×8.1=40.5h
157.95=40.5h
÷40.5 both sides
h=3.9
