NEED HELP ASAP

anonymous · Answer

help pleassssssssssse

hartnn · Answer

when triangles are similar, their corresponding sides and perimeter are proportional.

anonymous · Answer

so what would it be then? I'm a bit confused @hartnn

ganeshie8 · Answer

you familiar with the term, scale factor ?

anonymous · Answer

not at all @ganeshie8

ganeshie8 · Answer

ok, then make a proportion of two correspondng part ratios like this :-

$\large \frac{15}{5} = \frac{?}{12}$

ganeshie8 · Answer

? is the new perimeter of ABC. can you solve

anonymous · Answer

36? @ganeshie8

ganeshie8 · Answer

perfect !

anonymous · Answer

thanks ! @ganeshie8 could you help me with another if I need help?

ganeshie8 · Answer

also we can confirm the answer by seeing that, the side of ABC is 3 times the side of DEF. so perimeter also will have to be 3 times larger. ya sure ask

anonymous · Answer

okay @ganeshie8

ganeshie8 · Answer

so, left flag is larger. have a look at one corresponding side in each of the flag.

left flag = 12
right flag = 4

that means, left flag side is 3 times larger than right flag eh ?

anonymous · Answer

yeah

ganeshie8 · Answer

so left flag's perimeter also will be 3 times larger than right flag

left flag perimeter = 3*right flag perimeter
                             =  ?
