(sorry , letters of keyoard 2 letters after V stopped workigi) tried , got ,30
l=50
-reath=30
if -reath=height
so,30 =30

Answer 2

Let  height of the wall = x meter
Then the area of the walls = 250*x m²
 The cost of painting wall= 250*x*10 Rs
ATQ  250*x*10= 15000
                      x=6 m
Height of wall is 6 m
