Question

Arrange 5625 plants in such a way that number of rows is equal to number of plants in each row. How many rows will be there? 2 Marks 75

Answer 1

Answer:

Number of Plants Planted in Each Row = 75

Step-by-step explanation:

Let the number of rows be y

Given,

Total Number of Plants = 5625

Number of Rows = Number of Columns = y

So,

Total Number of Plants = y×y = 5625

=> y² = 5625

=> y = √(5625)

=> y = √(3×3×5×5×5×5)

       = 3×5×5

       = 75

Hence,

Number of Plants Planted in Each Row = 75

Answer 2

Let us imagine, there are x no.of columns. So there will be x nos. of rows. Now plants have been planted in x nos. of rows and in x nos. of columns. Thus

X multiplied by x =5625

x^2 = 5625

x = 75

Answer There are 75 columns and 75 rows
