We can find the side length of square 3 by dividing by 4, which is 9.
Then, we find the side length of square 2 by dividing it by 4, which is 12.
To find the AREA of square 1, we do a^2+b^2=c^2. This is basically adding up area of square 1 and square 2 to get square 3.
a^2+b^2=c^2
9^2+12^2=c^2
81+144=225
So the area is 225 units.
Answer:
Tonya cut the cylinder vertically and David cut it diagonally.
So this is our table:
-----------------
x-values | a b c d e f |
-----------------
y-values | g h i j k l |
-----------------
You can know that the values in the table are proportional if:
