What is the perimeter of a regular octagon with sides 4 mm long?
32 mm
How do you make one eighth equal parts on a 4 by 4 sguare?
Draw an asterisk in it. That is, draw a horizontal line halfway between the top and the bottom, draw a vertical line halfway between the two sides, draw diagonal lines fro the opposing corners.
How do you represent the fraction four tens using a model or number line?
Draw a line segment 10 cm long. measure the first 4 cm and make that part darker.
How long is 4 meters in mm?

How can you draw a rectangle?
It is made up out of 4 lines, 4 corners and 4 right angles. Haha, this is all I can say on how to make a rectangle. Draw a horizontal line along the page (say 5 cm long) Using a pair of compasses and a straight edge construct a 90o angle at the left end of this line; or alternatively measure 90o using a protractor at the left end. Draw another line from the left end vertically up this 90o angle (say 2 cm). Using a pair of compasses set to the length of the long horizontal line, put the point at the top of the vertical line and draw an arc over the right end of the horizontal line (roughly the height of the vertical line above it) Now setting them to the length of the vertical line, put the point on the right end of the horizontal line and draw an arc to intersect the previously drawn arc. With the straight edge, join the top of the left vertical line, and the right of the horizontal line, tot he point where the arcs cross. Rub out the arc construction lines and you'll have a rectangle left.
