Q
Q: If the length of an object is doubled, what happens to its area?
Solution:
If the length is doubled, the area increases by a factor of four (A = length²).
Steps: 6
Show Steps
Step 1: Understand that area is calculated using the formula A = length × width.
Step 2: If we only consider a square or rectangle, we can say that both the length and width are the same (length = width).
Step 3: If the length of the object is doubled, we can represent the new length as 2 × length.
Step 4: The new area will be calculated as A = (2 × length) × (2 × length).
Step 5: Simplifying this, we get A = 4 × (length × length) = 4 × original area.
Step 6: Therefore, when the length is doubled, the area increases by a factor of four.
