The red line represents the amount of money that you have to spend. That must be shaded below.
Solve for hypotenuse
Hypotenuse =
Substitute 3 for A and 4 for B
Solve exponents
3^2 = 9
4^2 = 16
Add
9 + 16 = 25
Solve square root
= 5
5 is your answer
325 lb brought
15 lb each
so
325/15 = 21.6 people
or 21 people can get a full 15 lbs and 1 person gets .6 of 15 lb or 9 lb

The area of the whole square board is one side squared: 20 squared = 400 cm squared
The probability is therefore equal to %
