Question

The area of a rectangle is 96 cm². If the breadth of the rectangle is 8 cm, find its length and perimeter.

Answer 1

Step-by-step explanation:

We know Area of rectangle = length × width

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.

Answer : the perimeter of rectangle is 40 cm.

Answer 2

Answer:

length =12cm

perimeter =40cm

Step-by-step explanation:

length=area/breadth

perimeter=2(length+breadth)
