Question

The area of a rectangle is 96 cm into 2. If the breadth of the rectangle is 8 cm, find its lenght and perimeter.

Giv explanation

Answer 1

Answer:

Area of rectangle =L×b

According to question

96=L×8

L=96/8

L=12

PERIMETER OF RECTANGLE=2(L+B)

=2(12+8)

=2×20

=40

Answer 2

Answer:

Length of rectangle = 8 cm.

Width of rectangle is w cm.

 

Area of rectangle = 96 cm^2

Area of rectangle = length × width

 

96 cm^2 = 8 cm × w cm.

8w = 96  

w = 96/8  

w = 12 cm.  

The width of rectangle is 12cm.  

Now Perimeter of rectangle

 

Perimeter = 2 (length + width)

 

Perimeter = 2 ( 8 cm. + 12 cm)

 

Perimeter = 2 ( 20 cm)

Perimeter = 40 cm.
