Question

Find the ratio of the figures below! Please help, I will fan and give a medal to the best/right answer

Answer 1

@amistre64 could you help with this?!

Answer 2

So ratio of what? areas? sides? volumes?

Answer 3

@luckythebest the areas

Answer 4

ok so is it given that the triangles are similar?

Answer 5

sorry I thought I said that, I guess I didn't lol I've been working on school work all day :/

Answer 6

yes @luckythebest

Answer 7

Ok. so we can see that 10 units and 8 units sides are corresponding sides.

There is one concept.

"Ratio of areas of 2 similar triangles is the ratio of SQUARES of corresponding sides."

So Ar(big)/Ar(small) = 10^2/8^2

if you can find the value. cheers! :)

Answer 8

So would I write it as 10^2/8^2 or would I actually do the math so it would be 100/64?! Lol, I'm kind of confused...

Answer 9

@luckythebest

Answer 10

no lol its directly 100/64 = 25/16.

You want i can prove the above concept here itself.

Answer 11

but yeah u need to do that math of writing it as 100/64 = 25/16.

Ratio hence = 25:16.

Answer 12

I think I understand it now, thank you @luckythebest

Answer 13

@HeyImKae but be very careful, that concept applies only to similar triangles, and only the corresponding sides. dont do it for any random non-similar triangles.
