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

What is the perimeter of a square if the area is 49cm squared?
Area = 49 cm2 so side = sqrt(49) cm = 7 cm and therefore, perimeter = 4*side = 28 cm.
What is the area of a square that has a perimeter of 28?
Perimeter = 28 = 4s = 4 x 7 Therefore, each side is 7cm long Area = s x s = 7 x 7 = 49cm squared

What is the smallest figure with a perimeter of 20 but the smallest possible area?
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...
How do you find the perimeter of a triangle if you know the area?
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.

What is the largest and the smallest perimeter possible for a rectangle with a area of 24cm2?
The smallest perimeter is 4*sqrt(24) = approx 19.6 cm There is no largest perimeter.

How do you describe a rectangle with the given area that has the smallest perimeter?
square
What type of rectangle has the smallest perimeter for the same area?
A square.
What is the largest and smallest perimeter possible for a rectangle with a area of 42?
Largest = 86, Smallest 26
What is the largest and smallest perimeter possible for a rectangle with a area of 100?
The smallest is just over 40 units. At 40 units it is no longer a rectangle but a square. There is no largest perimeter.
What is the area of a 7cm square?
area= 7cm x 7cm = 49cm^2
If the area is 350square feet what is the perimeter?
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.
