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 m?)?
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
