Question

find the breadth of a rectangle whose perimeter is 170 cm and length is 50 cm​

Answer 1

we know that

2(l+b)=170

2(50+l)=170

50+b=170/2=85

b=85-50 =35m

Answer 2

☆ Solution ☆

Given :-

• The perimeter of the rectangle is 170 cm.

• The length of the rectangle is 50 cm.

To Find :-

• The breadth of the rectangle .

Step-by-Step-Explaination :-

Let,

• The breadth of the rectangle be b

As we know that :-

Perimeter of the rectangle = 2 ( length + breadth )

Where,

• Perimeter of the rectangle = 170 cm

• Length of the rectangle = 50 cm

• Breadth of the rectangle = l

Putting the respective value,

170 = 2 ( 50 + b )

170 = 100 + 2b

2b = 170 - 100

2b = 70

b = 70/2

b = 35

Hence,

The breadth of the rectangle is 35 cm .
