Questions & Step-by-Step Solutions

What is the length of the diagonal of a rectangle with sides 6 cm and 8 cm? (2020)
  • Step 1: Identify the lengths of the sides of the rectangle. Here, the length is 8 cm and the width is 6 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: Diagonal = √(8² + 6²).
  • Step 4: Calculate the squares of the lengths: 8² = 64 and 6² = 36.
  • Step 5: Add the squares together: 64 + 36 = 100.
  • Step 6: Take the square root of the sum: √100 = 10.
  • Step 7: Conclude that the length of the diagonal is 10 cm.
