What Is Area?

This is the measure of the surface size calculated in the 2D dimension. It can be measured in several units, including square meters, sq. kilometers, sq. feet, sq. miles, hectares, and acres. This metric is used in agriculture, building, and road construction.

Even daily, we often use this kind of calculation to figure out how much paint we need to cover the wall or what size the carpet should be to fit our living room space. Whenever you want to know the area, the calculator is at your service!

How to Calculate Area?

It’s easy to make calculations when it comes to spaces that have a square or rectangular shape, yet things get more complex when you have circle-shaped or triangular space to deal with.

For square, use the formula A=a2, where A is the area, and a is the length of the space side.

For rectangular, calculate the area with this formula A= ab, where a and b are the lengths of the sides.

For circular, you need the A=πr formula, where π=3.14 and r – the space radius.
