1st question:
The formula for area of a triangle given 3 side lengths is A = √(s(s-a)(s-b)(s-c))
where s = (a+b+c)/2
s = (50 + 45 + 25) /2 = 120/2 = 60
Area = √(60(60-50)(60-45)(60-25)
Area = √(60*10*15*35)
Area = √315000
Area = 561.25
Rounded to nearest whole number = 561 square meters.
2nd question:
b. Increasing the number of trapezoids increases the accuracy of the area calculation
c. The area of all the trapezoids can be added together to find the area under the curve.
