The six sides would be:
2 sides of 14*4=56cm^2, 112 in total
2 sides of 4*6=24cm^2, 48 in total
2sides of 14*6=84cm^2, 168 in total
112+48+168=328cm^2

Step-by-step explanation:
This is a difficult graph to make, because none of the points are on any grid intersections.
At the left (s=0), it starts 1/4 of the distance up from 7000 toward 8000.
At the right (s=10), it crosses 3/10 of the distance up from 9000 toward 10,000.
Her totals sales were "x", now, if she sold "x", and made a 30% of "x" which is 1800, that simply means, "x" is the 100%

solve for "x"
Answer:
If you've learnt sin(A+B) = sinAcosB + cosAsinB,
sin(4u)
= sin(2u+2u)
= sin(2u)cos(2u) + cos(2u)sin(2u)
= 2 sin(2u) cos(2u).
