Can you help me get the answer I’m just not sure if I’m right

zhenek [66]

Answer:

430 $in^{2}$

Step-by-step explanation:

To find the area, use the area for a parallelogram formula:

A = bh, where A is the area, b is the length of the base, and c is the height of the parallelogram.

Next, substitute the values of the base and height:

A = 20in. * 21.5 in.

Finally, simplify the multiplication:

A = 430 $in^{2}$
