Answer:
145769 ft²
Step-by-step explanation:
This involves the use of Heron's formula to find the area of the triangle, given the side lengths. We will need to find the semi-perimeter of the triangle, which is half of the full perimeter.
s = semi-perimeter
s = (650+760+450)/2
s = 1860/2
s = 930
Now, using this we put it into Heron's formula to find the area.
A = √((930)(930-650)(930-760)(930-450))
A = √(930(280)(170)(480))
A = √21248640000
A = 145769.1325
A = 145769
The area of the parcel is 145769 ft²
2x = 10√3
=> x = 10√3 / 2
=> x = 5√3
hence missing side of triangle is 5√3
