Length is doubled and breadth is same.
Length is doubled and breadth is same.
✓
Answer
If the length is doubled and the breadth is same.
Let the initial length and breadth be $l$ and $b$, respectively.
Original area $= l \times b = lb$
Now, length is doubled and breadth remains same.
Therefore New length $= 2l$
New breadth $= b$
New area $= 2l \times b = 2lb$
Thus, the area of the rectangle will become $2$ times that of its original area.
