Answer:
is the expanded form, anything else you need?
Step-by-step explanation:

To work out the mean, add them all up and divide by however many values there are:
(18+54+42+(76x2)+46) / 6 = 52
To work out the median, order them from largest to smallest or vice versa and find the middlest value.
18, 42, 46, 54, 76 ,76
(46 + 54) / 2 = 50
The mode is the most frequently occurring number, so it would be 76.

Step-by-step explanation:
Answer: Option A. 65 m^2
Solution:
Sides: a=10 m, b=14 m, c=20 m
Area: A=?
A=sqrt [p(p-a)(p-b)(p-c) ]
Semi-perimeter: p=(a+b+c)/2
p=(10 m+14 m+20 m)/2
p=(44 m)/2
p=22 m
A=sqrt [ (22 m)(22 m-10 m)(22 m-14 m)(22 m-20 m)]
A=sqrt [ (22 m)(12 m)(8 m)(2 m) ]
A=sqrt [ 4,224 m^4 ]
A=64.99230723 m^2
A=65 m^2
