From the question it is given that total number of plants arranged = 1024
Let us assume number of plants in each row be ‘a’
As per the condition given in the question,
Number of plants in a row is the same as the number of rows i.e. ‘a’
Then,
Total number of plants = a × a
1024 = a2
By taking square root on both side,
a = √(1024)
a = √(32 × 32)
a = √(32)2
a = 32
∴The number of plants in each row is 32.
