We know 1 meter = 3.28084 feet
So 1 square meter = 3.28084 × 3.28084 square feet.
Now to convert from square feet to square meters, we need to divide by 3.28084 × 3.28084.
The area given in the news paper advertisement is 1330 square feet.
So to convert to square meters we divide by 3.28084 × 3.28084
We get
1330 square feet = 
Hence 1330 square feet of area is equal to 123.56 square meters.
Well, if you just divide 4000 by 50, you can see that the answer will come out as:
<em><u>80
</u></em>~TO check: 80 multiplied by 50 would come out to the answer of 4,000.

Answer:
27,600
Step-by-step explanation:
We use the following formula:-
Number of permutations of r from n
= nPr
= n! / (n-r)!
I am assuming you don't allow repeated letters in the 4 letter codes.
Take S as the first letter. Then we have 3 letters extra out of 25 letters.
Using the above formula the possible ways of doing this is
25! / (25 - 3)!
25! / 22!
= 25*24*23
= 13800.
The same number is obtained if the first letter is a T.
So the answer is 2*13800
= 27,600
