Question

the area of four walls of room is 57m2. If the room is 5m long and 3m wide, find the height of the room​

Answer 1

Answer:

the formula is 2* h (l+b)

so, the = 2*h(5+3)m

=2*h (8)m

= 57/(8)*2

=57/16

= 3.56

Answer 2

Answer:

4.75 m

Step-by-step explanation:

area of four wall is 57 m2

so area of one wall=57/4=14.25 m

we have width of all four walls =3 m

let length is x m

so are= l*w

14.25=x*3

x=14.25/3=4.25 m
