Freddy the farmer has three fields. One field is an equilateral triangle, one field is a circle, and one field is a square. The square field is 75% larger in area than the triangular field, and 50% larger in area than the circular field. In order to completely fence all three of the fields, exactly 4000 metres of fencing is required.
What is the total area of all three fields, in square metres? Please round to the nearest whole number

Correct to the nearest whole number in square meters:
Area of Triangle = 79,454
Area of Circle = 158,909
Area of Square = 105,939
As a check, add the perimeters: (Nearest whole number in meters)
1,285 + 1,413 + 1,302 = 4,000

That goes under homework help...
Triangular field=1
Circular field=1.75*2/3
Square field=1.75
Area for each number=sum divided into total area=4000/(4+(2/3))=~857
Triangul... oops.... Forget everything I said
Area of square=b^2
Area of triangle=b*((b^2-(.5b)^2)^.5)
Area of circle=pi*r^2
I don't think you need that though.. I keep reading this wrong and am making it too hard :-/
Perimeter of square=4(area^.5)
Perimeter of triangle=ooo... that's a toughy...
Forget it, I'm getting too distracted ^_^
