Answer 2

Step-by-step explanation:

area of outer rectangle = 12 x 10 = 120 square metre.

The area of inner rectangle = 6 x 4 = 24 square metre. (length = 12 - 3 - 3 & breadth = 10 - 3 - 3)

Area of the corridor = The area of outer rectangle - The area of inner rectangle

= 120 - 24 = 96 square metre.
