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?

Correct answer:

x =  13.33
y =  16.67

Step-by-step explanation:

x/y=4/5 (x+y)/2=15

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

(x+y)/2 = 15
5•x = 4•y

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

x = 40/3 ≈ 13.333333
y = 50/3 ≈ 16.666667

Our linear equations calculator calculates it.
y=2 154 2 15/(4+5)=16.67
