A hall's carpet area is 300 square metres and its length is one metre more than twice its breadth. Setting up this problem gives a:
AQuadratic equation
BLinear equation
CCubic equation
DCircle equation
Answer & Solution
Correct answer: A. Quadratic equation
1. Let the breadth be x, so the length is 2x plus 1.
2. Area is x times 2x plus 1, which has an x squared term.
3. So the problem gives a quadratic equation.
