Question

2
Perimeter of a rectangle is 157 m. If the length is 47 m, find its breadth.​

Answer 1

Answer:

31.5 m

Step-by-step explanation:

Let the breadth be 'b'.

   Perimeter = 2(length + breadth)

Here,

⇒ 157 = 2(47 + breadth)

⇒ 157/2 = 47 + b

⇒ 78.5 - 47 = b

⇒ 31.5 = b

Answer 2

Answer:

31.5

Step-by-step explanation:

Given, P= 157cm

L= 47m

B=?

WKT, perimeter of rectangle is 2(l+b)

157= 2(47+B)

157=94+2B

157-94 = 2B

63/2 = B

therefore breadth = 31.5
