Q:
# How big is 15 square meters?

**A typical room in a house could be 15 square meters.** Considering the formula for the area of a rectangle provides a means for estimating how large a given area may be.

The area of a surface is defined as the amount of material needed to "cover" it completely. A square meter is the basic unit of area of the metric system. The formula for calculating the area of a rectangle is: A = l x w, where "A" is the area, "l" is the length and "w" is the width. If you assume that the area of a rectangle is 15 square meters, you can estimate the values for the length and width, which yields 15 square meters. Choosing a value of 5 meters for the length and 3 meters for the width, produces 15 square meters, the size of a medium-sized room.
