Step-by-step explanation:

4.5 miles each day except Sunday is 6 days per week

In 2 weeks, she runs 12 days

4.5 miles × 12 = 54 miles

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.
