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
Yes if the dimensions were 3cm by 13cm
390. There are 10 mm in 1 cm, so 39 x 10 = 390.
If the octagon is regular, then one side is 39 and there is 8 side, it will be 39*8The answer is 312 cm squaredIf it isn't a regular octagon, then there is no solution
