Question

The perimetre of a rectangular is 200 cm . Its length is three time its breath . Find its length and breadth. ​

Answer 1

Answer:

25.75 cm

Step-by-step explanation:

perimeter= 200cm

let the breadth be x

then length= 3x

also, perimeter= 2(l+b)

= 200= 2(3x+x)

= 200/2 = 3x+x

= 100 = 4x

= x = 100/4 = 25

so, breadth = x = 25cm

so, breadth = x = 25cmlength = 3x = 3× 25 = 75cm

Answer 2

Answer:

Let the breadth be x

so, length be 3x

A.T.Q

2(l plus b)=200

6x plus 2x =200

8x=200

x=25

so,

breadth = 25 cm

and length=3x

=3×25=75 cm.
