Detailed Solution
Download Solution PDFदिलेल्याप्रमाणे:
आयताची लांबी आणि रुंदी अनुक्रमे 8% आणि 5% ने वाढली आहे.
वापरलेली संकल्पना:
A%आणि B% च्या सलग दोन वाढीनंतर अंतिम टक्केवारीत बदल = \((A + B + {AB \over 100})\%\)
गणना:
क्षेत्रफळातील अंतिम टक्केवारी वाढ = \(8 + 5 + \frac {8 \times 5}{100}\) = 13.4%
∴ क्षेत्रफळ 13.4% ने वाढेल.
