Question

A KIDZ society started a campaign "Plant the Plants" with 1621 saplings. They bought the saplings and

to the number of saplings in each row. Find the number of rows if 21 saplings were left out after the
arrangement.

Answer 2

Answer:

Here is your answer, buddy

To find the required numbers of rows, first substrate 21 from 1621 and find it's the square root.

.°. 1621 - 21 = 1600

√1600 = 40(square root of 1600 is 40)

thus, 40 rows could be formed
