Question

A man plants 5184 orange trees in his garden and arranges them so that there are as many rows as there are orange trees in a row. How many rows are there in the garden?

• A. 70
• B. 72
• C. 75
• D. 81

Answer 1

The correct option is B 72

Let the number of orange trees in a row $=x$.
Then, the number of rows in the garden $=x\therefore x\times x=5184\Rightarrow x^2=5184\Rightarrow x=\sqrt{5184}=72$
