Marks: +1, -0

If the length of a side of a square is equal to that of the diameter of a circle, then the ratio of the area of the square to that of the circle is

(\Take \π= {22}/{7} )

Solution:

(1) Let length of a side of square be 2a units. Radius of the circle will be a unit.
So, the ratio of area of the square to that of the circle

= {( {\Side})^{2}}/{\π {a}^{2}}

= {(2 a)^{2}}/{ {22}/{7} × a^{2}}= {4 × 7}/{22}= {14}/{11}
