You can put this solution on YOUR website! +=
You're give c - the hypotenuse or diagonal - as 6m
You're also given one side as 4m.
Plug in the numbers. +=
16 + = 36
Subtract 16 from each side = 20
Take the square root of each side
b = roughly 4.47 (rounded)
If you want to be more precise, b=the square root of 20
