If you're talking about a five sided figure, just add up your figures.
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
9cm is longer because 86mm is equal to 8.6cm.
There is no answer
Area is length times width. So... 9x9=81
9cm + 5cm + 9cm + 5cm = 28cm
9cm
Perimeter = 6cm + 6cm + 9cm + 9cm = 30cm
it is 81cm
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2

10mm=1cm therefore 90mm=9cm
9cm is longer because 86mm is equal to 8.6cm.

9cm
1cm more because 9cm+1cm = 10cm
