Jordan estimated that his paper airplane would fly 42 feet. It actually traveled 50 feet. What was the percent error?

topjm [15]

$\huge \mathcal{ Answer࿐}$

Error (e) = 50 - 42 = 8 feet

assumed value (a) = 42 feet

$\boxed{ \mathrm{ \% \: error = \dfrac{error}{assumed \: value} \times 100}}$

$\mathrm{ \% \: error =\dfrac{8}{42}} \times 100$

$\mathrm{ \% \: error = \dfrac{800}{42} }$

$\mathrm{ \% \: error = 19.04 \%}$

Looking at the attachment, we'll determine entire hexagon area with this formula:
area = apothem^2 *Number of sides * tan(180/n)
area = 17.32^2 * 6 * tan (30)
area = 299.9824 * 6 * 0.57735
area = 1,039.16903184 
Now we subtract the triangle area (16*20 = 320)
shaded area = 1,039.16903184 -320 = 719.16903184 
answer is D
