Question

the area of a rectangular field is 4500m;² find its perimeter if it is known that its length is five times the breadth.

Answer 1

let lenght be 5x and breadth be x
A/Q
area of a rectangular field =l×b
4500m^2=5x × x
4500m^2=5x^2
4500/5=x^2
root 900=x
30=x




length = 5x=5×30=150
bradth =x=30
c
perineter of rectàngular = 2 (l+b)
=2(150+30)
2×180
=36
