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.

Answer:
Step-by-step explanation:
x² - x -6 = x² + 2x - 3x - 3*2
=x(x + 2) - 3(x + 2)
= (x + 2 )(x - 3)
