Answer 2

Answer:

The answer is 7m

Step-by-step explanation:

since the area of walls is 350

we have 4 walls of

which 2 walls will be having area ( h x l )

and 2 walls will be having area ( h x b )

where l is length and b is width and h is height

so..

350 = 2( h x l ) + 2( h x b )

350 = 2hl + 2hb

350 = 2h( l + b )

350 = 2h( 15 + 10 )

350 = 50h

Therefore h=7
