I'm assuming you're looking to find the expanded form of the number?
This number is in scientific notation. The easiest way to convert it to a normal number is to move the decimal place 14 to the right. I've attached a picture showing how to do this. You should get 630,000,000,000,000
There's a faster way to do this - notice that you need to move the decimal 14 to the right, and there's one number already after the decimal place. Therefore, 13 places will be filled with zeros. So, just write out 63 and add 13 zeros.

Answer:
Step 1 :
Split the figure into 3 parts
part 1: triangle with base = 7 + 2 + 6 = 15in, height = 7in
part 2 : Rectangle with breadth = 3 + 6 + 2= 11in and length 8in
Part 3 :Rectangle with breadth 2in and length 9in
Step 2 :
find the area of each part
Area of part 1
Area of part 2
Area of part 3
Total area = 52.5 + 88 + 18 = 158.5 sqaure inches
