Any parallelogram has the area of the length between the left and right side times the length from the top to the bottom.

Here the horizontal length is easy, it's just 6. it tries to trick you witht he vertical length. You want the straight up nd down line from the top and bottom, which is that 8 on the right. so the area is 6*8

The cross section of a hopper for containing balls is shown.

svp [43]

ANSWER

$14 \: ft$

EXPLANATION

Let the top of the hopper be

$l \: ft$

Then, by the cosine rule,

${l}^{2} = {13}^{2} + {15}^{2} - 2(15)(13) \cos(59.5 \degree)$

We evaluate to get,

${l}^{2} = 169 + 225 - 390\cos(59.5 \degree)$

${l}^{2} = 394 - 197.94$

${l}^{2} = 196.06$
Take positive square root of both sides to get,

$l = \sqrt{196.06}$

$l = 14.00$
