Question

the Perimeter of a rectangle is 200cm.its length is three time its breadth . find the length and breadth.​

Answer 1

Answer:

let the breadth be x

let the length be 3x

Perimeter=2(l+b)

200=2(3x+x)

200/2=4x

100=4x

100/4=x

25=x

Therefore,the length is 25×3=75cm

the breadth will be 25cm

please mark me as the brainliest ,if my answer is correct

Answer 2

Step-by-step explanation:

Perimeter of Rectangle= 200cm

Let the breadth be 'b'

Then the length according to the condition will be= 3b

Perimeter of Rectangle = 2(l+b)

=2(3b+b)

200cm=2×4b

200cm=8b

b= 200/8

b= 25cm

Hence,

breadth, b=25cm

length, l= 3b= 3×25

=75cm
