What is the length of the diagonal of a rectangle with sides 3 cm and 4 cm? (2020)

What is the length of the diagonal of a rectangle with sides 3 cm and 4 cm? (2020)

Step 1: Identify the lengths of the sides of the rectangle. Here, one side is 3 cm and the other side is 4 cm.
Step 2: Use the formula for the diagonal of a rectangle, which is Diagonal = √(length² + width²).
Step 3: Substitute the values into the formula. This means we will calculate √(3² + 4²).
Step 4: Calculate 3², which is 9.
Step 5: Calculate 4², which is 16.
Step 6: Add the results from Step 4 and Step 5. So, 9 + 16 = 25.
Step 7: Now, take the square root of 25. This gives us √25.
Step 8: The square root of 25 is 5.
Step 9: Therefore, the length of the diagonal of the rectangle is 5 cm.
