Trapezium

The length of the base and the height size of the base of the trapezium is at ratio 5:3:2, the content area of the trapezium is 128 cm2. Calculate the length of the base and the height of the trapezoid.

Correct answer:

a =  20 cm
c =  12 cm
v =  8 cm

Step-by-step explanation:

a:c:v=5:3:2 S=128 cm2  S=a+c2 v S=5k+3k2 2k S=4k 2k S=8k2  k=S/8=128/8=4  a=5k=5 4=20 cm
c=3k=3 4=12 cm
v=2k=2 4=8=8 cm   Verifying Solution:  S1=a+c2 v=20+122 8=128 cm2
