Answer:
The median is 72
Step-by-step explanation:
The median is the middle of a sorted list of numbers. If there is an odd number of values, the median is the value at the middle. Otherwise, it is the mean between the two middle values.
In this question:
Scores: 86, 67, 62, 82, 64 and 77
Sorted: 62, 64, 67, 77, 82, 86
Middle elements: 67 and 77
Median: (67 + 77)/2 = 72
The median is 72

Answer:

Step-by-step explanation:
step 1
Find the scale factor
we know that
If two figures are similar, then the ratio of its corresponding sides is equal to the scale factor 
Let
z----> the scale factor
x----> corresponding side of the larger trapezoid
y----> corresponding side of the smaller trapezoid

we have


substitute

step 2
Find the area of the larger trapezoid
we know that
If two figures are similar, then the ratio of its areas is equal to the scale factor squared
Let
z----> the scale factor
x----> area of the larger trapezoid
y----> area of the smaller trapezoid

we have


substitute
