Please please help me

Answer 1

The area of a parallelogram is given by

$A=bh$

Now, if we consider the 9.9 inches side as the base, then the height is the one labeled with 5.5 inches.

If instead we choose the 11 inches side as the base, the height is h.

So, we can express the area in this two equivalent ways:

$A = 9.9\cdot 5.5 = 11\cdot h$

Solving for h, we have

$h = \dfrac{9.9\cdot 5.5}{11} = 4.95$
