एक आयत की लंबाई चौड़ाई से (6) अधिक है और क्षेत्रफल (72) है। यदि चौड़ाई (x) है, तो समीकरण क्या होगा?
A rectangle has length (6) more than its breadth and area (72). If the breadth is (x), what is the equation?
Explanation opens after your attempt
Correct Answer
A. \(x^2+6x-72=0\)
Concept
The length is (x+6) and the area is (x(x+6)=72). Therefore \(x^2+6x-72=0\).
Why this answer is correct
The correct answer is A. \(x^2+6x-72=0\). The length is (x+6) and the area is (x(x+6)=72). Therefore \(x^2+6x-72=0\).
Exam Tip
लंबाई (x+6) होगी और क्षेत्रफल (x(x+6)=72) होगा। इसलिए \(x^2+6x-72=0\) है।
