1cm = 10mm, so 4cm = 40mm. 1m = 100cm or 1000mm.
It is an equilateral triangle
96 sq. cm
45mm because 1 cm= 10mm so 40mm= 4cm and there's 45mm there which= 4,5cm.... :)

1cm = 10mm, so 4cm = 40mm. 1m = 100cm or 1000mm.
there are 10 millimetres in each centimetre. so 40/10 gives 4cm in 40mm.
There are 1000 millimetres in a metre, and 100 centimetres in a metre. So 1cm is the same as 10mm. So 4cm 40mm.
4cm
4cm = 0.00004km
Depends on the size of the eraser
Exactly 4 no more and no less but there are 40mm in 4cm
Millimetres and millimetres are the same measurement. Therefore, 160 millimetres is equal to 160 millimetres.
It depends what units you use for each side ! A 1cm x 15cm rectangle has a perimeter of 16cm. So does a 2cm x 4cm one ! If you start using millimetres, there are many more possibilities !
Four.
4cm
Yes (apart from units):If the side of a square is 4cm then itsperimeter is 4cm + 4cm + 4cm + 4cm = 4 x 4cm = 16cm;area is 4cm x 4cm = 16cm2
