The correct option is B 24
Total area of the square tiles
= 36 x 1 = 36 sq. m
The dimensions of different rectangles formed with the area 36 sq. m are
1 × 36, 2 × 18, 3 × 12, 4 × 9, 6 × 6.
For minimum perimeter of the formed shape(rectangle), the difference between the measure of the adjacent sides should be minimum.
For this case, the measure of the length and the breadth will be equal.
The length and breadth of the rectangle should be 6 m.
Perimeter of the rectangle = 6 + 6 + 6 + 6 = 24 m
