$\boxed{\boxed{\mathbf{330 cm^2}}}$
____________________________________

$\underline{\large\textbf{Given :}}$

l (length) = 12m
b (breadth) = 10m
h (height) = 7.5m

=================================

$\bf\underline{\large\textbf{To Find: }}$

Area of 4 Walls of Cuboidal room.
=================================

$\bf\underline{\underline{\Large\mathfrak{Solution :}}}$

$\underline{\textit{Using the Formula,}}$

$\boxed{\mathbf{2(l + b)h}}$

$\underline{\textsf{Putting the Values in the Formula, we get,}}$

$\mathsf{2(12+10)7.5}$

$\mathsf{=> 2(22)7.5}$

$\mathsf{=>(22)(15) }$

{Multiplying 2 and 7.5 to make calculations easier}

$\mathsf{=> 330}$
