Question

if the area of square field is 441 m sq. find its perimeter in cm​

Answer 1

Step-by-step explanation:

area of square field =441m sq

area of square field =441m sq area of square field=side ×side

area of square field =441m sq area of square field=side ×side 441=side²

area of square field =441m sq area of square field=side ×side 441=side²sq root of 441=side

area of square field =441m sq area of square field=side ×side 441=side²sq root of 441=side21m =side of square field

area of square field =441m sq area of square field=side ×side 441=side²sq root of 441=side21m =side of square field permeter square field =4×side

area of square field =441m sq area of square field=side ×side 441=side²sq root of 441=side21m =side of square field permeter square field =4×side =4×21

area of square field =441m sq area of square field=side ×side 441=side²sq root of 441=side21m =side of square field permeter square field =4×side =4×21 =84m

Answer 2

To find : perimeter of square field  in cm .

Given :  area of square field is $441$ m sq. find its perimeter in cm​ .

Solution :

• As per given data we know that area of square field is $441$ m sq.
• We know that all four sides of square are equal .
• If ' $a$ ' is the side of square then area of square is given by,
• Area of square $= a^{2}$
• Therefore, by substituting the value in above formula we find side of square .

         $441 =a^{2} \\a = 21$

• Now , side of square is $21\ m$ .
• Perimeter of square of field = $4a$

                                                       $= 4\times 21\\= 84 \ m$

• Converting perimeter of field in centimeters :

        $84 \ m= 84 \times 100\ cm$

                 $= 8400\ cm$

Hence, perimeter of square field  in cm is $8400\ cm$ .
