If the area of a parallelogram is given by the formula base times height, what happens to the area if the height is halved?
  1. The area remains the same
  2. The area doubles
  3. The area is halved
  4. The area increases by 25%

Questions & Step-by-Step Solutions

If the area of a parallelogram is given by the formula base times height, what happens to the area if the height is halved?
  • Step 1: Understand the formula for the area of a parallelogram, which is Area = base × height.
  • Step 2: Identify what happens when the height is halved. If the original height is H, then halving it gives us a new height of H/2.
  • Step 3: Substitute the new height into the area formula. The new area becomes Area = base × (H/2).
  • Step 4: Simplify the new area formula. This can be rewritten as Area = (base × H) / 2.
  • Step 5: Notice that (base × H) is the original area. Therefore, the new area is half of the original area.
  • Step 6: Conclude that if the height is halved, the area of the parallelogram is also halved.
  • Area of a Parallelogram – The area of a parallelogram is calculated using the formula: Area = base × height.
  • Effect of Changing Height – Halving the height directly affects the area, resulting in the area being halved.
