Answer:

1843.2 m²

Step-by-step explanation:

For rectangle-1 ; L1 = 7.5 m

                           A1 = 720 m²

               ∵ Area, A1 = L1 * B1

                          720 = 7.5 * B1

                         B1 = 720/7.5 = 96 m

Now for rectangle-2 ; L2 = 12 m

            ∵      both the  rectangle are similar

            ∴       L1 / B1  = L2 / B2

            ⇒    B2 = ( L2/L1)*B1

                         = ( 12/7.5)*96

                         = 153.6 m

NOW, AREA OF SECOND RECTANGLE, A2 = L2 * B2

                                                                         = 12 * 153.6

                                                                         = 1843.2 m²
