A park needs to make a cement walkway that cuts through the park diagonally. If the length of the park is 300 meters and the width is 400 meters, how long will the walkway be?

Answer 1

Just good ol' Pythagoras ....

L^2 = 300^2 + 400^2

L = .....

Answer 2

Is it 500 m? Square root of 250000 = 500

Answer 3

yes, notice that 300, 400, and 500 is simply a multiple of 3,4, 5

3,4,5 would form the smallest right-angled triangle with integer sides.
