To find the other side of the rectangular field, we can use the Pythagorean theorem, which states that in a right-angled triangle:

$\text{Diagonal}^2 = \text{Side 1}^2 + \text{Side 2}^2$

Given:

• One side of the rectangle (Side 1) = 15 m
• Diagonal = 17 m

Let the unknown side be $x$ (Side 2).

By the Pythagorean theorem:

$17^2 = 15^2 + x^2$

$289 = 225 + x^2$

Now, solve for $x^2$:

$x^2 = 289 - 225 = 64$

Take the square root of both sides:

$x = \sqrt{64} = 8$

So, the other side of the rectangular field is 8 meters.

Here are some related questions for further practice:

1. What is the area of this rectangular field?
2. What is the perimeter of the rectangular field?
3. How would the result change if the diagonal was 20 m instead of 17 m?
4. How can the Pythagorean theorem be applied to non-rectangular shapes?
5. Can you derive the length of the diagonal if both sides of a rectangle are known?

Tip: Always check that the largest value in a right triangle is used for the diagonal when applying the Pythagorean theorem.
