1 metre = 100 centimetres 54.5cm and 45.5cm (54.5 - 45.5 = 9cm) A revised answer: Let's call the unknown lengths (x+9) and x (x+9)+x = 100 x+x = 100-9 2x = 91 x = 45.5 So the lengths are indeed 54.5cm and 45.5cm
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
