The correct option is A 72 sq m
● The rectangle is divided into 4 equal parts.
● Let’s find the area of one small rectangle.
● Area of one small rectangle = Length × Width
=3 m×6 m
=18 sq m
● The area of all 4 parts will be the same.
● Total area = Number of parts × Area of one part
=4×18 sq m
=72 sq m
Hence, option D is correct.
