permeter of rectangle=40

Answer 2

Answer :

Perimeter of rectangle is 18cm

Given :

• Length of rectangle is 5cm
• Breadth of rectangle is 4cm

To find :

• Perimeter of rectangle

Solution :

As we know that,

• Perimeter of rectangle = 2(l + b)

Where, l is length and b is breadth

》Perimeter of rectangle = 2(l + b)

》2(5 + 4)

》2(9)

》18 cm

Hence , Perimeter of rectangle is 18cm

Verification :

》Perimeter of rectangle = 2(l + b)

》18 = 2(5 + 4)

》18 = 2(9)

》18 = 18

Hence , Verified
