Question

what is perimeter of rectangle with length= 18 cm and breadth = 12 cm​

Answer 1

Given :

✰ Length of Rectangle (L) = 18cm

✰ Breadth of Rectangle (B) = 12cm

To Find :

✰ Perimeter of Rectangle

Solution :

✰ As we Know that Perimeter of rectangle is 2 (Length + Breadth), Where Length is 18cm and Breadth is 12cm. By using this formula we can easily find the Perimeter of Rectangle.

Perimeter of Rectangle = 2(L + B)

Where,

• Length (L) = 18cm

• Breadth (B) = 12cm

→ Perimeter = 2 (18 + 12)

→ Perimeter = 2 × 30

→ Perimeter = 60cm

∴ Perimeter of Rectangle is 60cm

Answer 2

Given :

• Length of Rectangle {L} = 18cm
• Breadth of Rectangle {B} = 12cm

To Find :

• Perimeter of Rectangle

Solution :

✰ As we know that, Perimeter of the Rectangle is given by 2(Length + Breadth) . Now in this, question Length and Breadth of the Rectangle are given and we have to find the Perimeter of the Rectangle . So simply we will put the given values in the formula to find the Perimeter of the Rectangle.

⠀⠀

⟶⠀⠀Perimeter of Rectangle = 2(L + B)

⟶⠀⠀Perimeter of Rectangle = 2(18 + 12)

⟶⠀⠀Perimeter of Rectangle = 2 × 30

⟶⠀⠀Perimeter of Rectangle = 60cm

⠀⠀

So, Perimeter of Rectangle is 60cm

___________________

What if we need Area also ?

⠀⠀

⟶⠀⠀Area of Rectangle = L × B

⟶⠀⠀Area of Rectangle = 18 × 12

⟶⠀⠀Area of Rectangle = 216cm²

⠀⠀

So, Area of Rectangle is 216cm²
