How long is the perimeter of a 2cm by 3cm rectangle?
10cm 2l + 2w 4+6=10cm
How do you make a shape with a perimeter of 9cm?
Well, honey, making a shape with a perimeter of 9cm is as easy as pie. You could have a triangle with sides measuring 3cm, 3cm, and 3cm. Or you could have a rectangle with sides measuring 2cm and 2.5cm. Just remember, the perimeter is the sum of all the sides, so get those measuring tapes out and get creative!
What is the mean of 4cm 2cm 1cm 3cm 5cm?
Mean = sum(X)/n = 15cm/5 = 3cm

What is the area of 2cm 2cm 4cm 6cm 2cm 2cm 4cm?
It is impossible to answer this question because the question could refer to an object in 7-dimensional hyperspace or it could be an irregular heptagon (or other possible shapes in 3, 4 5 or 6 dimensions). In anything but 7-d space, its exact shape is indeterminate and so the area cannot be calculated. To understand the indeterminacy, a 2cm + 2cm + 2cm + 2cm shape could be a rhombus or a square, and these will have different areas. Without the angles, there is no way of knowing which.
