Area is calculated by the formula w x h (width times height). The term '12 inches squared' is referring to a calculation being made. When you square something, you are multiplying the same number two times. In the case of 12 inches squared, you will be calculating 12 inches x 12 inches.

The square root of 13 is expressed as √ 13 in the radical form and as 13^{½} in the exponent form. The square root of 13 rounded to 5 decimal places is ±3.60555.

A square inch (in^{2} or sq. in.) is a unit of measurement of area. 1 square inch is equal to the area of a square with sides that measure 1 inch: A square area is a measurement made up of two lengths.

The square root of 13 is expressed as √ 13 in the radical form and as 13^{½} in the exponent form. The square root of 13 rounded to 5 decimal places is ±3.60555.

Multiply the length and width together. Once both measurements are converted into metres, multiply them together to get the measurement of the area in square metres.

4 square metres A = 4 m^{2}. The room has an area of 4 square metres. If you say that this is 4 metres squared what you mean is an area which has the length of 4 metres and you are multiplying it by a breadth of 4 metres which would give you an area of 16 square metres and not 4 square metres.
