(D) The area of a rectangle is given by the product of its length and width: $	ext{Area} = 	ext{length} 	imes 	ext{width}$.Given: $	ext{length} = 1.5\, cm$ (which has $2$ significant figures) and $	ext{width} = 1.203\, cm$ (which has $4$ significant figures).Calculating the product: $1.5 	imes 1.203 = 1.8045\, cm^2$.According to the rules of significant figures in multiplication, the final result should have the same number of significant figures as the measurement with the least number of significant figures.Since $1.5$ has $2$ significant figures, the result must be rounded to $2$ significant figures.Rounding $1.8045$ to $2$ significant figures gives $1.8\, cm^2$.

If the length of a rectangular plate is $1.5\, cm$ and the width is $1.203\, cm$, then its area is ............ $cm^2$.
