Question: What is the length of the diagonal of a rectangle with vertices at (0, 0), (4, 0), (4, 3), and (0, 3)? (2021)

Options:

Correct Answer: 5

Solution:

Length of diagonal = √[(4-0)² + (3-0)²] = √[16 + 9] = √25 = 5.

What is the length of the diagonal of a rectangle with vertices at (0, 0), (4, 0), (4, 3), and (0, 3)? (2021)

Step 1: Identify the coordinates of two opposite corners of the rectangle. Here, we can use (0, 0) and (4, 3).
Step 2: Use the distance formula to find the length of the diagonal. The formula is: Length = √[(x2 - x1)² + (y2 - y1)²].
Step 3: Substitute the coordinates into the formula. Here, (x1, y1) = (0, 0) and (x2, y2) = (4, 3).
Step 4: Calculate (x2 - x1) which is (4 - 0) = 4.
Step 5: Calculate (y2 - y1) which is (3 - 0) = 3.
Step 6: Square the results from Step 4 and Step 5. So, 4² = 16 and 3² = 9.
Step 7: Add the squared results together: 16 + 9 = 25.
Step 8: Take the square root of the sum: √25 = 5.
Step 9: The length of the diagonal of the rectangle is 5.
