एक आयत की लंबाई (x+3) और चौड़ाई (x) है। क्षेत्रफल (10) हो तो सही द्विघात समीकरण कौन-सा है?

A rectangle has length (x+3) and breadth (x). If its area is (10), which quadratic equation is correct?

Explanation opens after your attempt
Correct Answer

A. \(x^2+3x-10=0\)

Step 1

Concept

The area is (x(x+3)=10), which gives \(x^2+3x-10=0\). In geometry questions, form the equation using the formula.

Step 2

Why this answer is correct

The correct answer is A. \(x^2+3x-10=0\). The area is (x(x+3)=10), which gives \(x^2+3x-10=0\). In geometry questions, form the equation using the formula.

Step 3

Exam Tip

क्षेत्रफल (x(x+3)=10) होगा जिससे \(x^2+3x-10=0\) मिलता है। ज्यामिति प्रश्न में सूत्र से समीकरण बनाएं।
