Answer 2

Answer:

Option (d) is correct

Step-by-step explanation:

from figure (1),

9 = 3²

36=6²

25=5²

16=4²

Now,

√9+√36+√25+√16

= 3+6+5+4

= 18

from figure (2),

25=5²

16=4²

1=1²

64=8²

Now,

√25+√16+√1+√64

=5+4+1+8

= 18

From figure (3),

9 = 3²

1=1²

64=8²

Now,

√9+√x+√1+√64 = 18

=> 3+√x+1+8 = 18

=> 12+√x = 18

=> √x = 18-12

=> √x = 6

On Squaring both sides of the equation, we get

=> ( √x )²= 6²

=> x = 36

Therefore,

Option (d) is correct
