Bases

The length of the bases trapezium are in ratio 4:5. Length of midline is 15. How long are the bases of a trapezoid?

Result

x =  13.33
y =  16.67

Solution:

Solution in text x =

(x+y)/2 = 15
5 x = 4 y

x+y = 30
5x-4y = 0

x = 403 ≈ 13.333333
y = 503 ≈ 16.666667

Calculated by our linear equations calculator.
