For a square, the area is the length of a side squared and the perimeter is 4 times the length. If the area is 49, then the length of a side is 7. The perimeter is then 4 times 7, or 28.
Area = 49 cm2 so side = sqrt(49) cm = 7 cm and therefore, perimeter = 4*side = 28 cm.
The length of each side is seven (7) meters.
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
The area of a square is equal to the length of each side squared. So, in this case, 7 x 7 (72) = 49 square meters.
