A picture can help you sort this out.
Draw point E on CD so that AE ⊥ CD. Then the distance DE is 8cos(60°) = 4, and the height AE is 8sin(60°) = 4√3. The length of CD is 8+2×4 = 16. The area of the trapezoid is the product of the height and the average base length:
... A = (b1 +b2)/2×h = (8 cm + 16 cm)/2×(4√3 cm) = 48√3 cm² ≈ 83.14 cm²

Staff and line are names given to different types of functions in organizations. A "line function" is one that directly advances an organization in its core work. This always includes production and sales, and sometimes also marketing.
Let the number sold of veggie pizza be a
The number sold of cheese pizza be b
a+b=25…1
A+7=b…2
Sub 2 into 1
a + a+7 = 25
2a+7=25
2a=18
a=9
Sub a=9 into 2
9+7=b
b=16
They sold 9 veggie pizza and 16 cheese pizza
