Question

The perimeter of a triangle is 48 inches and the sides are in the ratio of 3:4:5. Find the length of the longest side.

4
9
16
20

Answer 1

Any ideas?

Answer 2

9 maybe

Answer 3

All the other sides would be less than 9 then. But not even 9*3 is 48. So thats incorrect.

Answer 4

im not sure tbh

Answer 5

You are saying that 9 is the longest length. But its not because even if all the sides were 9 the perimeter wouldnt be 48.

Answer 6

ohhh 16

Answer 7

Nope. Remember that all the other sides will be less than 16. 16 is only the length of the LARGEST side.

Answer 8

so its 4 then?

Answer 9

is 4+4+4=48? no
