Elise walks diagonally from one corner of a square plaza to another. Each side of the plaza is 50 meters. What is the diagonal distance across the plaza?

50√2 ≈ 70.71067812

Step-by-step explanation:

Since it's a square, it has right angles, therefore use Pythagorean theorem to solve this problem

a² + b² = c²

Since all sides are 50 meters, a and b will be 50

50² + 50² = c²

c is the diagonal

2500+2500 = c²

5000 = c²

Root both sides

you'll get 50√2
