If a leaf initially measures 5 cm² and undergoes arithmetic growth at a rate of 0.2 cm² per day, what will be its area after 10 days?
A
7 cm²
B
15 cm²
C
25 cm²
D
10 cm²
Correct Answer
Option D
Detailed Explanation
In arithmetic growth, the formula L_t = L_0 + rt can be used. Here, L_0 = 5 cm², r = 0.2 cm²/day, and t = 10 days. Thus, L_t = 5 + (0.2 * 10) = 7 cm².
