How will you expand the swimming pool 4 times more

[muralichmk]

hi,
take a = 1 m as the side of the squre.
now the area of the existing pool is 1sq.mt.

to get the pool 4times more, add an equilateral traingle each side of the square, now the trees come in the middle of the sides.

length of a side now = 2 mts.
area = 4 sq. mts.

bye.

length of the side is not equal to 2, length of the side becomes square root of 2(daigonal of original square) and the area becomes 2 sq.mts.
we can make the swimming fool 2 times, still keeping it square and without cutting trees.
Its immposible to make it 4 times!!!!!!!!!! question it self is wrong
