Question

the breath of a rectangle garden is one third of its length.if the perimeter of the garden is 160m,find its length and breadth.

Answer 1

let the length of the rectangular garden = x

breadth = one third of length= x/3
perimeter of the garden = 160 m

2(length + breadth) =160

2( x+x/3) =160

2(4x/3)=160

8x/3=160

x= 160*3/8

x= 20*3

x= 60

therefore 
 length= x= 60m

breadth = x/3 = 60/3 = 20 m

Answer 2

Answer:

let the length of the rectangular garden = x

breadth = one third of length= x/3 perimeter of the garden = 160 m

2(length + breadth) =160

2(x+x/3) =160

2(4x/3)=160

8x/3=160

x= 160*3/8

x= 20*3

X= 60

therefore

length= x= 60m

breadth = x/3 = 60/3 = 20 m
