Question

21. The areas of similar
triangles are 144cm2, & 25cm2
than ratio of their
corresponding altitude
12/5
none
25/144
144/25​

Answer 1

Answer:

The ratio of areas of given similar triangles =25:16

And we know that, ratio of areas of two triangles is same as the ratio of squares of their corresponding sides

∴ Ratio of the corresponding sides of the similar triangles =

16

25

=

4

5

=5:4

∴ The ratio of the perimeters of given similar triangles =5:4

Hence, the answer is 5:4.
