4.9 cm times the number of sides in the polygon. Simple!
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
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
It can be infinitely large. Consider a rectangle of length A cm where A ≥ 7 cm. And let its width be B = 49/A cm. Then its area is always A*B cm2 = A*49/A cm2 = 49 cm2. Let A = 10 cm, B = 4.9 cm so perimeter = 29.8 cm or A = 100 cm, B = 0.49 cm, perimeter = 200.98 cm or A = 1000 cm, B = 0.049 cm, perimeter = 2000.98 cm By making the rectangle infinitesimally thin and infinitely long, its perimeter can be increased without limit.

Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.Area = 49 cm2 => length of side = 7 cmThen perimeter = 4*7 = 28 cm.

49cm
they can be 49cm.

2.8 metres - 49 centimetres = 2.31 metres
0.49 metres as you said. This is 49cm or 490mm
area= 7cm x 7cm = 49cm^2
