Estimate how many 12 incj rulers will be about the same length as the object
It depends on how long the ruler is, but most rulers are 12 inches and 12 inches=1 foot...so the answer would be 4 rulers for 4 feet...thats a lot of fours :) I am presuming you are using 12inch rulers so as there are 12inches in a foot you will need 4 rulers

That depends on the size of the door. If the door is 7 feet long, it is the same length as 7 12-inch rulers, because 12 inches is equivalent to 1 foot.

There is a ruler to show the width of the page and one to show the length of a page. Rulers will also show when you are using text boxes. You can change the units shown on rulers. The options are inches, centimetres, milimetres, points and picas. The rulers can be used to set tabs, indents and margins.
