असमिकाओं \(x+y\le 4\), \(x\ge 0\), \(y\ge 0\) से बने त्रिभुज का क्षेत्रफल कितना है?
What is the area of the triangle formed by \(x+y\le 4\), \(x\ge 0\), \(y\ge 0\)?
Explanation opens after your attempt
Correct Answer
A. (8) वर्ग इकाई(8) square units
Concept
The intercepts are (4) and (4), so area is \(\frac{1}{2}\times 4\times 4=8\). Remember the intercept triangle formula.
Why this answer is correct
The correct answer is A. (8) वर्ग इकाई / (8) square units. The intercepts are (4) and (4), so area is \(\frac{1}{2}\times 4\times 4=8\). Remember the intercept triangle formula.
Exam Tip
त्रिभुज के intercepts (4) और (4) हैं, इसलिए क्षेत्रफल \(\frac{1}{2}\times 4\times 4=8\) है। परीक्षा में intercept triangle का formula याद रखें।
