Answer 2

Given :-

• base perimeter of the room = 34 m
• height of the room = 10 m

To Find :-

• area of four walls ?

Solution :-

we know that,

$\boxed{\bold{ perimeter \: of \:base = 2(l + b)}}$

$\bold{: \implies 2(l + b) = 34 \: cm } \: ......(i)$

and

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

now, put the value of 2(l + b) and h

$\bold{ : \implies 34cm \times \: 10 cm } \\ \\ \bold{: \implies 340 \: {cm}^{2} } \: \: \: \: \: \: \: \: \: \: \: \:$

hence, area of four walls of the room is 340 cm²
