176+176+39+39cm

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

Longer than your's will ever be, I you no what i mean.

There are 390 millimeters in 39 centimeters. This is because there are 10 millimeters in 1 centimeter.

390. There are 10 mm in 1 cm, so 39 x 10 = 390.

There are 10 millimetres in a centimetre. To convert mm to cm, you have to divide by 10. 390/10 is 39cm.

The rectangle is 23cm x 16cmHalf the perimeter is 78 / 2= 39cm (which is one side and one end).39 - 7 = 32cm32 / 2 = 16cm (one end)16 + 7 = 23cm (one side)Proof:(23 + 16) x 2 = 78cm the perimeter.

1 Inch = 2.54 cm Or 1cm = 0.393700787 inches So 39cm would equal 15.3543307 inches
