if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm

54cm

the area is 54cm squared. which is a little 2 at the top of where m in the cm finishes.

First, set up a few equations...2w + 2l = 54w = l/2With a little manipulation...l = 2wso therefore6w = 54w = 9and, substituting back in,l = 18

if one length is 9cm, the other length must be 6cm to make an area of 54cm. hence the perimeter is 9+9+6+6 = 30cm

20 x 2 = 4007 x 2 = 1440 + 14 = 54cmSo the perimeter is 54cm

54cm

9 centimetres,as 54/6 is 9

12 + 24 + 18 = 54cm (Or 0.54 metres)

False. 54cm = 540mm

yes,it is true...... 5.4mm = 54 cm

is 54cm=5.4mm

57cm X 54cm X 15 cm equals 7,156 square inches.
