How do you find 4 possible picture screens with whole number dimensions with a diagonal of 15 inches?:
:
Start with equation
x^2 + y^2 = 15^2
x^2 + W^2 = 225
y^2 = (225 - x^2)
y = sqrt%28225-x%5E2%29
:
Choose values for x that will give you an integer value for y
:
You can't unless you count x=15, y=0 and vice-versa
there are only two
x=12, y=9
x=9, y=12
