Area = 49 cm2 so side = sqrt(49) cm = 7 cm and therefore, perimeter = 4*side = 28 cm.
Perimeter = 28 = 4s = 4 x 7 Therefore, each side is 7cm long Area = s x s = 7 x 7 = 49cm squared

A 9 x 1 rectangle has a perimeter of 20 and an area of 9; A 9.5 x 0.5 rectangle has the same perimeter but an area of 4.75; You can go a long way along this road...
You cannot. For a given area, an equilateral triangle will have the smallest perimeter but that perimeter can be increased - without limit - without increasing the area.

The smallest perimeter is 4*sqrt(24) = approx 19.6 cm There is no largest perimeter.

A square.
square
Largest = 86, Smallest 26
The smallest is just over 40 units. At 40 units it is no longer a rectangle but a square. There is no largest perimeter.
area= 7cm x 7cm = 49cm^2
There is insufficient information to answer the question. For a given area, the perimeter depends upon the shape. For a given area, the circle will have the smallest perimeter. For polygons, regular polygons will have a smaller perimeter than an irregular one of the same area. Also, for regular polygons, the greater the number of sides, the smaller the perimeter.
