Question

the area of four walls of a hall is 266 square metre the length and the breadth of a hall are 12 and 7 respectively find the height of the wall​

Answer 1

Step-by-step explanation:

area of four walls = 2(l+b)h

266 = 2(12+7)h

266=2(19)h

266 = 38h

h = 266/38

h = 7m

Answer 2

Answer:

h=7m

Step-by-step explanation:

l=12m , b=7m , h=?

Area of four walls=2h(l+b)

=> 266 =2h(12+7)

=> 266 =2h*19

=> h =266/(19*2)

=> h =133/19

=> h =7m
