4cm
The area of a rectangle of sides 9cm and 10cm is:9cm x 10cm = 90cm2This is equivalent to 0.009m2
That octagon is obviously not a regular one, so we'd need to know the lengthsof all eight sides in order to work with it. But you've given us the lengths of onlyfour of them. So we don't have enough information to come up with an answer.
Area is length times width. So... 9x9=81
base x height = area 2 cm x 2cm = 2cm^2 (squared) :)
