Question

Sameer plants 7225 plants so that there are as many rows as there are trees in a row. How many trees are there in a row?

Answer 1

Hint: This is a tricky question. In this we just need to focus on the statement “as many rows as there are trees in a row”. The answer is hidden here only. If T is the number of rows then there are T trees in each row such that T multiplied by T will be the total number of plants. So let’s solve it!

Complete step-by-step answer:
Sameer has planted 7225 plants. But he planted them in a systematic manner. What did he do?
He planted the trees in different rows. But such that the number of rows is equal to the number of trees in each row. So if T is the number of rows as mentioned above then T will be the number of trees in each row.
Then we can say that,
\[T \times T = 7225\]
\[{T^2} = 7225\]
Now taking the square root we get,
\[T = 85\]
Thus, it concludes that there are 85 rows and there are 85 plants in each row.
So, the correct answer is “ 85”.

Note: Note that number of plants in each row is equal. Total number of plants are distributed equally thus it is like a square matrix. Now only the thing that can confuse us is the number of rows is not equal to the number of plants ; it is the number of plants in each row.
