The smallest known insect, a kind of fairyfly, has a body slightly longer than 1×10^-4 meters . The longest known insect, a kind of stick insect, has a body slightly longer than 6×10^-1 meters.

c

step-by-step explanation:

i think because what else can be a sample of every member

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

the answer is  

a.

28 ft2
