Tiana and Greg go for a walk in a rectangular park. They travel 4.3 km north from Point A and 7.2 km in distance diagonally across the park. How far do they have to walk to get back to Point A?

a²+b²=c²

a²+ 18.49 = 51.84 

a²= 51.84 - 18.49 

a²=33.35 

(square root both sides)

a = 5.8 km 

They will need to walk 5.8 km to point A.
