Question

A rectangle with length and breadth equal to 9 m and 4 m respectively has to be converted into a square having the same area. What will be the side of the square? (Give answer to two decimal places).

• A. 17.97
• B. 16.93
• C. 15.98
• D. None of these

Answer 1

The correct option is C

15.98

Area of rectangle $=9\times 4m^2=36m^2$ . Since, area of square = area of rectangle
therefore, Area of square $=36m^2$.

If the side of the square is a, then the area is $a^2$.

$a^2=36m^2$

$a=6m$
