1) Dear Expert, Find the least no. that must be subtracted from 5607 so as to get a perfect square. Also find the square root of the perfect square.

2) 2118 plants are to planted in a Garden in such a way that each row contains as many plants. Find the no. of rows and find the plants in each row.

1) For solving the question, we start by finding the square root of 5607 by the long division method as :

It can be seen that 74² < 5607

So, if we subtract remainder (131) from 5607, we get a perfect square 5607 – 131 = 5476 = 74².

Hence, 131 is the least number which must be subtracted from 5607 in order to get a perfect square.

2) Let there x rows in the garden.

So, number of plants in 1 rows = x

According to the given conditions,

Number of rows × Number of plant in each row = 2118

Hence, there must be 46 rows in the garden and each row contains 46 plants.
