Question

the area of a rectangle is 96cmsquare. if the breadht of the rectangle is 8cm,find its lenght and perimeter ​

Answer 1

Answer:

length = 12 cm

perimeter = 40 cm square

Step-by-step explanation:

area = length×breadht

96 = l × 8

l = 12 cm

perimeter = 2(length+ breadht)

p = 2( 12+8)

p = 40 cm square

Answer 2

To Find:-

Length and perimeter of the rectangle

Given:-

Breadth of the rectangle = 8cm

Area of the rectangle = 96cm^2

Formulae Applied:-

Area of a rectangle = L× B

Perimeter of a rectangle = 2(l+ b)

Solution:-

Let's take length as L

Breadth = 8cm

Area of the rectangle = 96cm^2

= (L × 8) = 96cm^2

= (L × 8) = 96

= 8L = 96

L = 96/8

L = 12cm

Therefore,

Length of the rectangle = 12cm

Now,

Length = 12cm

Breadth = 8cm

Perimeter of the rectangle = 2 (l + b)

= 2 (12 + 8)

= 2 (20)

= 40cm

Therefore,

Perimeter of the rectangle = 40cm

Important Formulae:-

➝ Area of a rectangle = L × B

➝ Area of a square = Side × Side

➝ Perimeter of a rectangle = 2 (l + b)

➝ Perimeter of a square = 4 × side
