Explanation: The perimeter of the rectangle can be calculated as follows: perimeter = 2(length + width) We have the width given = 5 units
Now, we need to get the length first then calculate the perimeter. Taking a look at the right-angled triangle, we can apply the Pythagorean theorem to get the length as follows: (hypotenuse)² = (length)² + (width)² (13)² = (length)² + (5)² (length)² = (13)² - (5)² = 144 length = +√144 = 12 units
Now, in the rectangle, we have: length = 12 units width = 5 units
