वर्ग \(0\leq x\leq 5\), \(0\leq y\leq 5\) में \(x+y\geq 4\) से मिलने वाले हल-क्षेत्र का क्षेत्रफल कितना है?
Inside the square \(0\leq x\leq 5\), \(0\leq y\leq 5\), what is the area of the solution region \(x+y\geq 4\)?
Explanation opens after your attempt
Correct Answer
C. (17) वर्ग इकाई(17) square units
Concept
The square has area (25), and the triangle below (x+y=4) has area (8). Therefore the remaining area is (17).
Why this answer is correct
The correct answer is C. (17) वर्ग इकाई / (17) square units. The square has area (25), and the triangle below (x+y=4) has area (8). Therefore the remaining area is (17).
Exam Tip
पूरे वर्ग का क्षेत्रफल (25) है और रेखा (x+y=4) के नीचे का त्रिभुज क्षेत्रफल (8) है। इसलिए बचा क्षेत्रफल (17) है।
