Answer:
4 hours
Step-by-step explanation:
X: Working hours by full-timer workers
Y: Working hours by Part-timer workers
Following the problem:
Y=2 and X-Y=2
so, clearing the equation and replacing Y value in it
X=2+Y => X=4 hours
You know the area of a trapezoid is given by the formula
A = (1/2)(b₁+b₂)h
Solving for h, you get
h = 2A/(b₁+b₂)
The area in both cases is 42 cm², so the height will be given by
h = (2*42 cm²)/(b₁+b₂)
15. h = (84 cm²)/(5 cm + 7.5 cm) ≈ 6.7 cm
16. h = (84 cm²)/(5.7 cm + 10 cm) ≈ 5.4 cm
