The length of a rectangle is five times of its breadth. If the area of the rectangle is 3125 cm2, then what is the length of the rectangle?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 125 cm.
Area of rectangle= length × breadth
Let the breadth & length of the rectangle be b & 5b
According to the question,
⇒ b × 5b = 3125
⇒ 5b² = 3125
⇒ b² = 625
⇒ b = 25 cm
So, length = 5b = 125
