Answer 2

Answer:

168 meter square

Step-by-step explanation:

Length of hall: 12 m

Width of hall: 10 m

Area of hall: 12 x 10 = 120 ms

Now,

Area of verandah + hall = (12 + 6)(10 + 6) = 18 x 16 = 288 ms

So,

Area of verandah only = 288 - 120 = 168 ms

Check:

[(12 + 3 + 3) x 3 + 10 x 3] x 2 = [54 + 30] x 2 = 84 x 2 = 168
