HERE IS YOUR ANSWER:

According to the question the formula will be:
A = lb + 2(l+b)xh
So, A = 12*10 + 2(12+10)*6.5
A = 120 + 44*6.5
A = 120 + 286
A = 406 m²

HOPE IT HELPS YOU.

the area of the four wall ,

= 2( length + wide ) × height

= {2( 12 + 10 ) × 6.5 } C M ^2

=(2 × 22 × 6.5 ) CM^2

= 286 cm^2

this is your answer
