The area of the rectangle is calculated through the equation,
A = L x W
in which A is the area, L is the length, and W is the width. Substituting the known values to the equation,
A = (20.0 m)(17.16 m) = 343.2 m²
Since, the least number of significant figures in the multiplier is 3, our answer ought to be in 3 significant figures. The answer to this item is therefore 343 m².
