Question

The length, breadth and height of the room, are 12 meter, 10 meter and 9 metre respectively find the area of 4 walls of a room. (Process required)

Answer 1

$\underline { \underline{ \sf{Given}}}$

• Length,l = 12 m

• Breadth,b = 10 m

• Height,h = 9 m

$\underline { \underline{ \sf{To \: find \: out }}}$

Find the area of four walls of a room ?

$\underline{ \underline{ \sf{Formula \: used }}}$

$\boxed{ \sf{Area \: of \: four \: walls = 2(l + b) \times h }}$

$\underline{ \underline {\sf{Solution}}}$

$\sf{Area \: of \: four \: walls = 2(l + b) \times h}$

★ Substituting the values in the above formula,we get:

$\sf{ Area \: of \: four \: walls = 2( 12+ 10) \times 9}$

$\rightarrow \sf{24 + 20 \times 9}$

$\rightarrow \sf{44 \times 9}$

$\rightarrow \sf{396 \: {m}^{2} }$

Hence, the area of four walls is 396 m².
