Question

5) The Perimeter of a rectangle is 64 cm, If its length is 17 cm, what is its breadth?
​

Answer 1

Step-by-step explanation:

perimeter of a rectangle=64

2(l+b). =64

2(17+b). =64

34+2b. =64

2b=64-34

2b=30

B=30/2

b= 15cm

Answer 2

Answer:

Breadth = 15 cm

Step-by-step explanation:

Given -

Perimeter of rectangle = 64 cm

Length of rectangle (l) = 17 cm

To find -

The breadth of rectangle (b)

Solution -

We know that Perimeter of rectangular = 2 (l+b)

so

2 (l+b) = 64 cm

=> l+b = 64/2 cm

=> 17 cm + b = 32 cm

=> b = 32 cm - 17 cm

=> b = 15 cm

Hence breadth of the rectangle = 15 cm.
