Question

can u plz answer this question 11th question​

Answer 1

Answer:

67

Step-by-step explanation:

formula for area of square =side²

area= 4489 then the side = √ 4489 = 67

Answer 2

Question:-

11)Find the length of the side of a square whose area is 4489 sq. cm.

Solution:-

Given,

Area of Square = 4489 sq. cm.

We have,

Area of the square

$= {(side)}^{2}$

Let side of square = x

Then,

${x}^{2} = 4489$

Transport (square) to RHS it becomes square root

$x = \sqrt{4489}$

$x = \sqrt{67 \times 67}$

$x = 67$

Therefore, Side of square = 67 cm

Question:-

12) How many numbers lie between the squares of 25 and 26

Solution:-

We know that,

${25}^{2} = 625$

And

${26}^{2} = 676$

No. of natural numbers lie between 625 and 676 is

$676 - 625 = 51$

So, 51 natural numbers lie between 625 and 676

Extra information:-

The number of natural numbers lie between 625 and 676 is 51

But there are other numbers called rational numbers whose number is infinite
