The perimeter of a rectangle is 40 cm. If its breadth is 8 cm, then what is the difference between the length and breadth of this rectangle?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 4 cm
Perimeter of Rectangle = 2(l + b)
Area of Rectangle = lenght x breadth
According to question
2(l + 8) = 40
l = 20- 8 = 12 cm
Difference between lenght and breadth = 12 - 8 = 4 cm
