Answer 1

Hlo friend... Cutiepie Here..

Nice question..

Here is ur answer :

Let the height be h.


Perimeter of Rectangular hall = 250 m

$2(l + b) = 250$


Area of 4 walls = 1500 m

$2(l + b)h = 1500$

$250h = 1500$


$h = \frac{1500}{250}$


$h =6$


Therefore, height will be 6 m.

HOPE IT HELPS YOU ....

Answer 2

perimeter =250
area of 4 walls =1500
area of one wall = 1500/4
=375
area of rectangle is =length * breadth
375= length *breadth-------(1)
perimeter of rectangle =2(lenght+breadth)
250=2(l+b)
250/2=l+b
125=l+b-----(2)
b-125=l
putting l value in 2 eq
125=b-125+b
2b =125+125
b=250/2
b=125
therefore height is 125
