Question

A rectangle whose length and breadth is 18m and 8m respectively has to be converted to a square with the same area. What will be the side of the square?

• A. 14
• B. 16
• C. 12
• D. 18

Answer 1

The correct option is C

12

Area of rectangle = Length x Breadth
$=18\times 8m^2=144m^2$

Since, the area of square = area of the rectangle.
Therefore, area of square $=144m^2$

Let the side of the square be "a".
Then area of the square = a${}^2$
$a^2=144=(12\times 12)m^2$
$a=\sqrt{{12}^2}=12m$
