Answer:
Length = 28 cm
Width = 70 cm
Step-by-step explanation:
let Breadth be x
let length be 2x/5
We Know,
Perimeter = 2( length + breadth )
so if we plug in what we know
196 = 2( 2x/5 + x )
If we simplify,
196 = 2( 2x/5 + 5x/5 )
196 = 2( 7x/5 )
196 = 14x/5
Multiply 5 both sides
196 x 5 = 14x
980 = 14x
980/14 = x
70 = x
x = 70 = breadth
2x/5 = 28 = length
