Question

the length and breadth of rectangle are in ratio 4:3. if its perimeter is 56 CM find dimensions of rectangle​

Answer 1

Answer:

Step-by-step explanation:

ratio of length and breadth is = 4:3

Let the length be 4x

and the breadth be 3x

Perimeter = 2( l+b )

 56cm      = 2(4x+3x)

     56cm  = 2*7x

     56cm  = 14x

           x     = 56/14

             x   = 4

So the length is = 4*4=16

       and the breadth is = 3*4=12

Answer 2

Answer:

Length = 16 cm

Breadth = 12 cm

Step-by-step explanation:

Let the length & breadth be 'x'

Length = 4x

Breadth = 3x

Perimeter of rectangle = 2(Length + Breadth)

56 = 2(4x + 3x)

56/2 = 7x

28 = 7x

28/7 = x

4 = x

Then,

Length = 4x = 4 × 4 = 16

Breadth = 3x = 3 × 4 = 12
