We need to calculate the area using two different methods.
00:04
For the first one, let's look at the one inches.
00:07
We know that one inch on the map is equal to 100 miles.
00:14
Let's do the same for the vertical because it's still one inch.
00:18
So for every one inches, we have 100 miles in the real world.
00:24
If we calculate the area in inches of this squared, the area is going to be 1 times 1.
00:30
Which is one inch squared.
00:35
If we calculate the area that this one inch square represents on real life, it's going to be 100.
00:42
Let's put an r for real life.
00:45
100 times 100, which is equal to 10 ,000.
00:53
1, 2, 3, square miles.
00:59
Now let's calculate the area enclosed in this squares made of, 1 over 4 inches over 1 over 4 inches.
01:06
This is the measurements of the grid paper we are using.
01:10
The area of this square is going to be equal to 1 over 4, which is the width times 1 over 4, which is the height.
01:18
So the area of the squares that we have in our grade are equal to 1 over 16 square inches...
