A student measures a rectangular room to be 20.0 m * 17.16m. which of the numbers below represents the room's area with the correct number of significant figures

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.
