Right Answer is: B
SOLUTION
If one small square in the grid is of area 4 sq. units, then its side would be 2 units.
Area of a square = side ×side
4 = Side
Side = 2 units
A rectangle covered 8 small squares in the grid. So, it's length= 8 units and breadth = 4 units
perimeter of a rectangle = 2( length + breadth)
= 2 (8 + 4) = 2 × 12 = 24 units
