centimeter
if you are after a metric measurement than millimetres^2
It depends on what you mean by size: its length, volume, surface area or even its mass.
no, Acres is an Imperial Unit for the measure of area. The metric unit for area is the square meter.
If you measure area by means of the metric system, you might be using square centimeters or square meters or square kilometers, depending upon the size of the area that you are measuring.
You would use a tool to measure the lengths of the sides or radii of the area and then use a formula to convert the lengths into an area. The tool would depend on the size of the object and the precision required. The tool could be an electron microscope, or a ruler, or a telescope and in general there would be no difference between a tool used to measure in the metric system or the imperial system. As an example of an unusual tool to measure area... in certain types of chemistry, the chemist needs to measure the area under a peak on a graph, and the traditional way of doing that is to cut the peaks out of the graph and weigh it on an analytical balance. Assuming the paper is fairly consistent in terms of density, the ratio of the weights is the same as the ratio of the areas.
To find the area of a book cover in metric units, the most appropriate unit to use would be centimeters. The formula for finding the area of a book cover would be: length x width.
metres
The metric unit of the meter would be the appropriate measure of the area of classroom. Calculating area involves multiplying the length (in meters) of the classroom's length and width. Area of the classroom would be in square (^2) meters.
meters2
Metres, to measure its length or width, square metres to measure its area.
yeah ofcourse what kind of question

Either the Imperial or metric system can be used to measure area (or anything else).
I think I saw that you tried to include that your units were in inches. this is not a metric unit to start. convert inches to centimetres. then multiply the length by the width to get your answer in cm^2, a metric unit
