If the length and breadth of a rectangle are doubled how does its peri...
Explanation:
When the length and breadth of a rectangle are doubled, the perimeter of the rectangle changes as follows:
Perimeter of rectangle = 2(length + breadth)
Let us assume the original length of the rectangle is L and the original breadth is B
So, the original perimeter of the rectangle = 2(L + B)
After doubling the length and breadth, the new length becomes 2L and the new breadth becomes 2B
So, the new perimeter of the rectangle = 2(2L + 2B) = 4(L + B)
The change in perimeter can be calculated as follows:
Change in perimeter = New perimeter - Original perimeter
= 4(L + B) - 2(L + B)
= 2(L + B)
Therefore, the change in perimeter is twice the original perimeter.
Since the original perimeter is multiplied by 2, the answer is option A: Tripled.
Therefore, when the length and breadth of a rectangle are doubled, its perimeter gets tripled.
When the length and breadth of a rectangle are doubled, the perimeter of the rectangle changes as follows:
Perimeter of rectangle = 2(length + breadth)
Let us assume the original length of the rectangle is L and the original breadth is B
So, the original perimeter of the rectangle = 2(L + B)
After doubling the length and breadth, the new length becomes 2L and the new breadth becomes 2B
So, the new perimeter of the rectangle = 2(2L + 2B) = 4(L + B)
The change in perimeter can be calculated as follows:
Change in perimeter = New perimeter - Original perimeter
= 4(L + B) - 2(L + B)
= 2(L + B)
Therefore, the change in perimeter is twice the original perimeter.
Since the original perimeter is multiplied by 2, the answer is option A: Tripled.
Therefore, when the length and breadth of a rectangle are doubled, its perimeter gets tripled.
