Question

find the perimeter and area of rectangle length 9cm breadth 1cm

Answer 1

Step-by-step explanation:

• perimeter of a rectangle = 2 (l+b)
• perimeter of a rectangle= 2 (9+1)
• perimeter of a rectangle= 2×10
• perimeter of a rectangle= 20 cm

• Area of a rectangle = Length × Breadth
• Area of a rectangle = 9×1
• Area of a rectangle = 9 cm

Answer 2

Given:

A rectangle of

• Length = 9 cm
• Breadth = 1 cm

To find :

• (i) Perimeter of Rectangle
• (ii) Area of Rectangle

Solution:

(i) As we know that,

Perimeter of Rectangle = 2(L + B)

Therefore, putting the values :

=> 2(9 + 1)

=> 2 (10)

=> 20 cm

Perimeter of the Rectangle = 20 cm.

(ii) As we know that,

Area of Rectangle = L × B

Therefore, putting the values :

=> 9m × 1m

=> 9cm²

Area of the Rectangle = 9cm²
