Do you ever wonder what the area of a notebook that you use for study? Is it a square or a rectangle? And how would you measure the length of its boundary? And have you seen a carpeting measuring the dimensions of a wooden block? Well, there are many applications where we measure an area and its boundary. Let’s study more in the section below.

**FAQ on Area and Its Boundary**

**Question 1: What does area mean in math?**

**Answer:** When we talk about geometry, we can define the area as the space that a flat shape or an object’s surface occupies. Thus, the area of a figure is the number of unit squares covering the closed figure’s surface. We measure the area in square units like square centimetres, square feet, square inches, and more.

**Question 2: How do you find the area in math?**

**Answer:** The most simple and also the most commonly used area calculations are for squares and rectangles. In order to find the area of a rectangle, one must multiply the height by its width. Similarly, for a square, one just needs to find the length of one of the sides and then multiply this by itself for finding the area. Remember that each side is the same length.

**Question 3: What is the area of shapes?**

**Answer:** The area of a shape refers to the space that encloses within the perimeter or the boundary of the specified shape. Thus, we calculate the area for several shapes by making use of math formulas.

**Question 4: What is the smallest unit of area?**

**Answer:** Square Millimeter is the smallest unit of area. The millimetre refers to a unit of length in the metric system, which is equal to one-thousandth of a meter which is the SI base unit of length. Thus, square millimetre (mm^2) is the smallest unit of area.
