Question

If the area of four walls of a rectangular room 4m is high 168m² what will be the perimeter of the room?

Answer 1

By Pythagoras property 168square=xsquare +4square 168square-4square =x square Perimeter=2*(l+b)

Answer 2

let us consider length= x.
l* b= area
x* 4= 168
x=168/4
x=42
2(l+b)=perimeter
2(42+4)
2(46)
perimeter =92
