Bases

The length of the bases trapezium is in the ratio 2:4. The length of the midline is 20. How long are the bases of a trapezoid?

Final Answer:

x =  13.33
y =  26.67

Step-by-step explanation:

x:y = x/y = 2:4  4 x = 2 y (x+y)/2 = 20  (x+4/2⋅ x)/2=20  3x=40  x=340​=13.33333333  x=340​≐13.333333=13.33
y=24​⋅ x=24​⋅ 13.3333=26.67
