I just need help with number 5 and and 4 and that’s it ☺️

Answer:
20 is the answer for number 4
Step-by-step explanation:
If the length is 10 and the height is 2 therefore the width is 10. Which equals a volume of 200[tex]cm^{2}[/tex] .
We can use the height and width to find the area of the shade part. The height (2) multiplied by the width (10) equals 20.
I hope this helps!
