Question

The perimeter of a rectangle is 128 centimeters and the length is 47 centimeters. Find the width of the rectangle.

Answer 1

GIVEN :

• perimeter of the rectangle = 128cm

• Length = 47 cm

To find :

• Width or breadth .

Solution :

• As we know that,

perimeter of the rectangle = 2 ( L + B )

=> 128 = 2(47+B)

=> 128 = 94 + 2B

=> 2B = 34

=> B = 34/2 = 17 .

Hence, the width is 17 cm

Answer 2

Step-by-step explanation:

given :

• perimeter of a rectangle = 128 centimeters

• length of perimeter = 47 centimetres

to find :

• Find the width of the rectangle = ?

solution :

formula of rectangle perimeter = 2× ( length + breadth)

• perimeter of rectangle = 2× (47 + breadth)

• perimeter of rectangle = 9 4 + 2 breadth

• perimeter of rectangle = 34

• perimeter of rectangle = 34/2

• breadth = 17
