Question

the lenght and breadth of a rectangle are in a 15:11 ratio if the lenght is 56cm more tjan the breadth find the oerimeter of the rectangle​

Answer 1

Answer:

Breadth = 41.06 cm (approx)

Perimeter = 194.12 cm (approx)

Step-by-step explanation:

Given :

Length and breadth are in ratio = 15:11

Length = 56 cm

To find :

(i) Breadth

(ii) Perimeter

Taken :

To find the Breadth use this equation -:

$\boxed{\sf{B=\dfrac{11}{15}\times56cm}}$

Where,

B = Breadth

After that to find the perimeter use this formula -:

$\boxed{\sf{P=2(L+B)}}$

Where,

P = Perimeter

L = Length

B = Breadth

Solution :

Breadth -:

$:\implies\sf{B=\dfrac{11}{15}\times56cm}$

$:\implies\sf{B=\dfrac{616}{15}}$

$:\implies\sf{B=41.06cm(approx)}$

So , the Breadth is 41.06 cm (approx) .

Perimeter -:

$:\implies\sf{P=2(56cm+41.06cm)}$

$:\implies\sf{P=2\times97.06}$

$:\implies\sf{P=194.12cm(approx)}$

So , the perimeter is 194.12 cm (approx) .
