212

Step-by-step explanation:

The given expression is

Substituting m = 3 and p = 10 in the expression

Now, simplify this expression

Therefore, the value of the expression is 212.

Third option is correct.

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.
