Length of a rectangle is 5 times of its breadth. If the perimeter of rectangle is 300 cm, then what will be the length of the rectangle?
Answer: A
Let the breadth be b, so the length is 5b. The perimeter of a rectangle is twice the sum of the length and the breadth, so 2(5b + b) = 12b = 300 cm, and b = 25 cm. The length is then 5 x 25 = 125 cm. Check: 2(125 + 25) = 300 cm, and 125 is five times 25. So the length is 125 cm, option (A). The value 25 cm is the breadth, and 100 cm, 150 cm and 250 cm do not give a perimeter of 300 cm with a length five times the breadth.
