[tex]A = (a^2 b)(3 a^2 b) = 3(a^2 b)^2 = 3a^4 b^2 ~~ \text{units}^2,[/tex]

Answer:

3a⁴b² units²

Step-by-step explanation:

Area of rectangle: L x B

=> Area of rectangle: LB

=> Area of rectangle = a²b x 3a²b

=> Area of rectangle = a² x b x 3 x a² x b

=> Area of rectangle = a² x b x 3 x a² x b

=> Area of rectangle = a² x a² x b x b x 3

=> Area of rectangle = a⁴ x b² x 3

Therefore, the area of the rectangle is 3a⁴b² units²
