A jogger running around a rectangular park takes a shortcut back to her car by jogging from one corner of the park to the diagonally opposite corner. If the park is 60yards by 45yards, how far is the shortcut?_____ yards
Q. A jogger running around a rectangular park takes a shortcut back to her car by jogging from one corner of the park to the diagonally opposite corner. If the park is 60yards by 45yards, how far is the shortcut?_____ yards
Identify sides as legs: Identify the lengths of the rectangle sides as legs of a right triangle, where the shortcut is the hypotenuse.
Use Pythagorean Theorem: We know:Length of the park: 60 yardsWidth of the park: 45 yardsUse the Pythagorean Theorem to find the hypotenuse (shortcut).
Apply Pythagorean Theorem: Apply the Pythagorean Theorem: a2+b2=c2602+452=c2
Calculate squares: Calculate the squares of the lengths:602=3600452=20253600+2025=c2
Add squares: Add the squares of the lengths: 3600+2025=5625c2=5625
Find square root: Find the square root of c2 to get the length of the hypotenuse:c2=5625c=75
