First, find the slope (m) = =
=
=
Now plug in ONE of the points and the slope into the point-slope equation:
y - y₁ = m(x - x₁); where (x₁, y₁) is the chosen point.
y - 5 = (x - 1) (I used (1,5) as the chosen point)
3(y - 5) = x - 1
3y - 15 = x - 1
3y -14 = x
-14 = x - 3y → x - 3y = -14
Answer: x - 3y = -14
Given:
The figure of a trapezoid.
Length of mid-segment = 5.5
Height of the trapezoid =
To find:
The area of the trapezoid.
Solution:
The area of a trapezoid is:
...(i)
Where, a,b are bases and h is the vertical height.
We know that is the length of the mid-segment.
Putting M=5.5 and in (i), we get
Therefore, the area of the trapezoid is units squared.
