Answer:
Can you retake the picture please, of the entire Problem?
Step-by-step explanation:
Area of aqua: A = bh/2 = (13.4cm) (4cm)/2 = 26.8cm2
Total area trapezoid: A = (a+b/2)h = ((13.4cm + 18cm)/2) 4cm = 62.8cm2
Area of purple = Total area - area of
aqua = (62.8cm2) - (26.8cm2) = 36cm2
3(10) + 5y = 20
5y = 20 - 30
5y = - 10
y = - 2
