Question

A man plants his orchard with $5625$ trees, and arranges them so that there are as many rows as there are trees in a row; how many rows are there?

• A. $65$
• B. $75$
• C. $85$
• D. $55$

Answer 1

The correct option is B $75$

It simply means that number of trees in a row & in a single coloum is same

Let this be $x$ then it will form a square field with side length $x$

Hence $x^2$ $=5625$

=> $x=75$
