A square wall tile has an area of 58,800 mm² between which two measurement is the length of one side

Given:

Area of a square wall tile; 58,800 mm²

To get an area of square simply multiply its side length by itself or raise it to the 2nd power.

Area = a²; a = side length.

58,800 mm² = a²

√58,800 mm² = √a²

a = 242.487 or 242.49 mm

The length of one side is between 242mm and 243mm.

14,700 millimeters

58,8000/4 = 14,700
