If a leaf is 50 cm ^2 in size and the growth rate per day is 5 cm ^2 , then its relative growth rate would become ------------.

Step-by-step solution

Initial size of the leaf, W₀ = 50 cm ^2 Absolute growth rate = 5 cm ^2/ day Relative growth rate is the growth per unit time expressed on a common basis, which is the initial size. Relative growth rate = Absolute growth rate Initial size 100 Relative growth rate = 5 50 100 = 10 % Answer: 10 %
