The smallest perimeter for a given area, such as 48 m², is achieved by a square. For a square, the area is calculated as ( A = s^2 ), where ( s ) is the length of a side. To find the side length, you take the square root of the area: ( s = \sqrt{48} \approx 6.93 ) m. The perimeter ( P ) is then calculated as ( P = 4s ), which gives approximately ( P \approx 27.72 ) m.

A square.
I think this means we have a shape with a perimeter 39cm and we are asked what is the smallest area. It is a rectangle of length 19.5cm and width zero. Or perhaps it should read area 49 cm squared., what is the smallest periimeter. A circle with 49=pi x r2. Then perimeter=pi x 2r
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...
48 square metres (48m2)

6 x 8
The smallest perimeter is 4*sqrt(24) = approx 19.6 cm There is no largest perimeter.
40
The smallest is just over 40 units. At 40 units it is no longer a rectangle but a square. There is no largest perimeter.
Largest = 86, Smallest 26
48m2
Type your answer here... give the dimensions of the rectangle with an are of 100 square units and whole number side lengths that has the largest perimeter and the smallest perimeter
