Step-by-step explanation:

divided 12 by three since it mirrors the shape on a smaller scale. you get 4. multiply that by five and there's your answer

u use similar figures to find it out

3/12=x/5

then u cross multiply

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
