If the areas of two similar triangles are in the ratio 25 : 36, then the ratio of their corresponding medians is यदि दो समरूप त्रिभुजों के क्षेत्रफलो का अनुपात 25 : 36 है, तब इनकी संगत माध्यिकाओं का अनुपात है
What will be the area A of the quadrilateral in each case with their diagonal d cm & the sum of their heights (h1+h2) cm.
i) d=20,(h1+h2)=10
ii) d=15,(h1+h2)=20
iii) d=20,(h1+h2)=25
iv) d=40,(h1+h2)=30
The correct statement with regard to H+2 & H−2 is
