Well lets go through what I know
- The answer to the first one (A) is 49 and were looking for 45
- Second questions answer (B) is 45 and that's the number were looking for so there's no need to go any further.
So the answer we are looking for is (B) 45
Hope this helps!
Pick’s Theorem is used to find the areas of figures on lattices easily. The formula is:
A = (B)/2 + I - 1, where B is the number of points on the border of the shape, and I is the number of points inside the shape.
Here, there are 8 points on the outside of the shape, and there are 12 points inside the shape. So, we do:
8/2 + 12 - 1 = 4 + 12 - 1 = 15 units squared.
We can check by finding the areas of the non-shaded region and subtracting that area from the whole rectangle area of 4 * 10 = 40:
4 * 1 + (3 * 1)/2 + 1 * 9 + (3 * 1)/2 + (9 * 2)/2 = 25
40 - 25 = 15, so we’re right!
The answer is 15 units squared, or choice (B).
It's done by contradiction
That is your reason

Answer:
????????.......?????????????????
if we asked questions and somone just ans the question wrongly for free points
therefore you can report the ans and delete the ans..
now a days many people are doing this...
