Question

Which of the following cannot be the area of a square with integral value side?
b) 2116 C) 3114 d) 3136
a) 3481​

Answer 1

Answer:

c) 3481

because area of square = 4a

and when you multiply some selected numbers by 4, they give 8,2,6,0,4

so only 3481 ends with a number which cannot be obtained by multiplying 4 to any integer...

hope you understand it, in case you don't, just let me know in the comments .... :)

Answer 2

Step-by-step explanation:

From the above options a , b , d are perfect squares.

The area of a square is a² where a is the side of square.

so area of a square is always a perfect square

Whereas square root of 'c' is not an integral value but a decimal value.

So 3114 is not area of the square
