Answer:

length is 44cm and breadth is 33cm.

Step-by-step explanation:

Let length be 4x and breadth be 3x.

2*(4x + 3x) = 154cm. ( perimeter is twice the sum of length and breadth ).

=> 14x = 154

=> x = 11

Therefore, length is 44cm and breadth is 33cm.

Answer:

The Length is 44 cm and Breadth is 33 cm.

Step-by-step explanation:

Given :

Ratio = 4 : 3

Perimeter = 154 cm

To find :

Length and Breadth

Solution :

Let the -

  • Length = 4y
  • Breadth = 3y

\boxed{\tt{Perimeter=2(Length+Breadth)}}

\implies 154 = 2(4y + 3y)

\implies 154 = 8y + 6y

\implies 154 = 14y

\implies y = 154/14

\implies y = 11

\rule{300}{1.5}

Length -

\implies 4(11)

\implies 44 cm

\rule{300}{1.5}

Breadth -

\implies 3(11)

\implies 33 cm

\therefore The Length is 44 cm and Breadth is 33 cm.
