Please note that a circumference is a linear measurement (for example, meters), while area is an area measurement (for example, square meters), so the "equality" depends on the units used. Anyway, all you need to do is write the expression for the circumference, and the expression for the area, then put an equal sign in between - since the problem states that the two are equal. Then solve this equation.

You can't convert that. One is a distance measurement, the other is a speed measurement. If it is a speed problem, use the formula distance = speed x time. In this case, you need to know how long it takes to advance those 2.2 meters. You also need to convert all the units to compatible units first - for example, using meters for distance, seconds for time, and meters/second for speed.
The area of Saint-Solve is 5,840,000.0 square meters.

Multiply them both, and you get 190 meters2.
the role of measurement is it can help us to solve some things accurate and precise
the unknown measurement of a side of a triangle
500 mg = 1/2 g = 0.5 gram
2.75 kilometers = 2,750 meters
you cant.
You can only "solve for n" if you have an equation, i.e. an equal sign - or an inequality.
