What are you asking?
if it's possible?
Yes you did, congratulations ;-)
You sum two vectors by summing the correspondent coordinates:

So, you have

Answer:
A. 804 cm²
Step-by-step explanation:
Formula :

A = 3.14 × 16²
A = 3.14 × (16 × 16)
A = 3.14 × 256
A = 803.84 cm²
A = <u>8</u><u>0</u><u>4</u><u> </u><u>cm²</u> (rounded)
So, the approximate area of the shown below is 804 cm² (A)
