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?
Answer & explanation
Correct answer: option 2
The perimeter of a rectangle = 40 cm.
If its breadth is 8 cm.
We know that,
Perimeter of a rectangle = 2(length + breadth)
Let the length of the rectangle be l.
Perimeter of the rectangle = 2(8 + l) = 40
l = 20 - 8 = 12 cm
