Calculate the area of a rectangle whose length is 6.00 m and breadth 5.2 m. Express the result to a proper number of significant figures.
Area of rectangle = Length × Breadth = 6·00 m × 5·2 m = 31·200 m2
As the number of significant figures in the least precise factor is two, therefore, the correct answer is 31m2.
