What happens the area and the perimeter of a rectangle if its length is doubled and bredth is not changed?
area = length x bredth
new_area = (2 x length) x bredth
= 2 x (length x bredth)
= 2 x area
→ doubling the length, but leaving the bredth unchanged doubles the area.
perimeter = 2 x (length + bredth)
new_perinter = 2 x (2 x length + bredth)
= 2 x (length + length + bredth)
= 2 x length + 2 x (length + bredth)
= 2 x length + perimeter
→ doubling the length, but leaving the bredth unchanged adds twice the original length (ie the new length of the rectange) to the perimter.

if the length and breadth are increased by 5 times each area becomes 25 times
What is the minimum perimeter of a polyomino with an area of 25?
The minimum perimeter of a polyomino is the perimeter of the most square shape that can be formed. If the area can't form a perfect square, the minimum is formed by wrapping the additional units in a spiral around the smallest square or rectangle. Since 25 happens to be a perfect square (the square root is 5), the perimeter would be 2(5+5)=20. If the area were between 26 and 30 that would add two additional sides which would be 20+2. After 30 the units would wrap to a new side of the 5x6 arrangement (still a perimeter of 22) yielding a new perimeter of 22+2 or 24, which would persist until it exceeds 6x6, and so on.

What happens to the area and the perimeter of a rectangle when the length and width are multiplied by 4?
Area is multiplied by 16. Perimeter is multiplied by 4.
What happens to the perimeter of a rectangle with a given area as it gets closer to being a square?
It decreases. viz: perimeter of 5 x 5 square is 20 units, perimeter of 12.5 x 2 rectangle is 29 units...
What happens to the perimeter of a rectangle when its length and width are quadrupled?
When the linear dimensions of a plane figure are quadrupled, its perimeter is quadrupled, and its area is multiplied by 42 = 16 .

What happens to the area of a rectangle when both dimensions are doubled?
It would be 4 times greater.To find this algebraically: let L be the length and W the width originallyA = L x WWhen both are doubled, the equation becomesA = (2L) x (2W) = 4LWThe area of the rectangle is quadrupled if both the length and width are doubled.
What happens to the perimeter and the area of a rectangle if the length and the width are multiplied by the same number Use diagrams to explain?
If the length and width of a rectangle are multiplied by the same number, then . . . -- the perimeter is multiplied by the same number -- the area is multiplied by the square of the numbner
