=36

Answer 2

GIVEN :

• Length of rectangle is 8cm
• Breadth of rectangle is 9cm

TO FIND :-

• Perimeter of a rectangle

FORMULA TO KNOW:-

• Perimeter of a rectangle = 2(l+b)

SOLUTION:-

Just putting down values in formula

Perimeter = 2(l+b)

• l = 8cm
• b = 9cm

P = 2(8+9) cm

P = 2(17) cm

P = 34cm

So, Perimeter of rectangle is 34cm

KNOW MORE :-

• In a rectangle opposite sides are equal
• Each angle in a rectangle is 90°
• Area of rectangle is length × breadth
• Sum of angles in a rectangle is 360°
