Question

A square garden has a length of ‘a’ meter, where ‘a’ is an integer. Which of these cannot be the area of the garden in (m2)?




17424

13689

74302

46225

Answer 1

Answer:

74302 is not possible area of square because the side of square coming in fraction i.e. not an integer number.

Step-by-step explanation:

Area of square = a×a = a^2

Since a is an integer so square root of area must be integer, otherwise that area is not possible.

√(17424) = 132 m, possible

√(13689) = 117 m, possible

√(74302) = 272.5839 m, not possible because it's not an integer

√(46225) = 215 m, possible
