Questions & Step-by-Step Solutions

What is the ratio of the areas of two similar triangles if the ratio of their corresponding sides is 3:4?
  • Step 1: Understand that the triangles are similar, which means their shapes are the same but their sizes are different.
  • Step 2: Note the ratio of the corresponding sides of the triangles, which is given as 3:4.
  • Step 3: Recognize that to find the ratio of the areas of similar triangles, you need to square the ratio of their corresponding sides.
  • Step 4: Calculate the square of the ratio 3:4. This means you take (3/4) and multiply it by itself: (3/4) * (3/4).
  • Step 5: Perform the multiplication: 3 * 3 = 9 (for the numerator) and 4 * 4 = 16 (for the denominator).
  • Step 6: Write the result as a fraction: 9/16. This is the ratio of the areas of the two similar triangles.
