Question

Q6: If the two similar triangles are in the ratio 3:7, then areas of these triangles will be in प्रश्न: यदि दो समरूप त्रिभुजों का अनुपात 3:7 है, तो इन विनों के क्षेत्रफलों का अनुपात ratio? होगा? Q7: If D, E and F are the mid points of sides BC, AC and AB of A ABC, then what will be ratio of the areas of triangles A DEF and A ABC? प्रश्र7:-AABC की भुजाओं BC, AC और AB के मध्य बिंदु D, E और Fहै । त्रिभुजों ADEF और AABC के क्षेत्रफलों का अनुपात क्या होगा?

​

Answer 1

Answer:

Correct option is

D

16:81

If two triangles are similar to each other, then the ratio of the area of this triangle will be equal to the square of the ratio of the corresponding sides of this triangle.

∴ The ratio between area of these triangle=(9)2(4)2=8116
