Math Problem Statement
The diagonal of this rectangle is 17 cm long and one leg is 8 cm long. How long is the other side?
Solution
We can use the Pythagorean theorem to solve this problem. The Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the diagonal in this case) is equal to the sum of the squares of the lengths of the other two sides.
The formula is: where:
- and are the lengths of the two legs (sides of the rectangle),
- is the length of the hypotenuse (the diagonal).
Given:
- The diagonal cm,
- One leg cm,
- The other leg is unknown.
Now, substituting the known values into the Pythagorean theorem:
So, the length of the other side is cm.

Tip: To remember the Pythagorean theorem, think of it as finding the "missing" side of a triangle when two sides are known. The equation always relates the squares of the sides.
