Answer 2

Given: area of square board = 1225 m²

Let side of square board be x

All sides of a square are equal

Area of square = side × side

=)1225 cm² = x×x

=)1225 cm²=x²

=)_/1225cm² = x ...(say a²=4 =) a=4½ =) a= +– 2)

=) +–35 cm =x( x= plus and minus 35 cm)

But side cannot be negative

=) x=35 cm

Each side of square= 35 cm

Hey be sure to mention both plus and minus though u can remove the negative one by an appropriate statement ... but for better Mark's it is mandatory

Hope it helps you
