Vedclass · Answer

(B) Absolute growth is the total growth of a system per unit time. Here,the initial area is $50 \, cm^2$ and the final area is $55 \, cm^2$. Absolute growth = $55 \, cm^2 - 50 \, cm^2 = 5 \, cm^2$. Relative growth is the growth per unit time expressed on a common basis (initial size). Relative growth = $\frac{	ext{Absolute growth}}{	ext{Initial size}} 	imes 100 = \frac{5 \, cm^2}{50 \, cm^2} 	imes 100 = 10 \%$. Therefore,the absolute growth is $5 \, cm^2$ and the relative growth is $10 \%$.
