The area of a rectangle is 125 cm2 and its length is 25 cm. What is its perimeter?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 60 cm
Area of a rectangle = length × breadth, so the breadth is area ÷ length; the perimeter is then \(2(l+b)\).
Breadth \(=125\div25=5\) cm
Perimeter \(=2(25+5)=2\times30=60\) cm
