How do I get the answer to question #5?

Answer:
7 cm
Step-by-step explanation:
Area of a parallelogram formula:
[tex]A=bh[/tex] where b is the base length and h is the height
Plug in known values (A=112, b=16 and h=x)
[tex]112=16x[/tex]
Divide both sides by 16 to isolate x
[tex]\frac{112}{16} = \frac{16x}{16}\\7=x[/tex]
Therefore, x is equal to 7 cm.
I hope this helps!
