The coordinates of the midpoint are the average of the coordinates of the given points.
So, the x coordinate of the midpoint is the average of the x coordinates of the given point:
And similarly, the y coordinate of the midpoint is the average of the y coordinates of the given point:
So, the midpoint is the point
The area of the composite figure is
Explanation:
From the given figure, we can see that the area of the composite figure = area of the rectangle + area of the triangle.
Area of the rectangle :
The formula is given by
where and
Substituting, we have,
Thus, the area of the rectangle =
Area of the triangle :
The formula is given by
where
and
Substituting, we have,
Thus, the area of the triangle =
Area of the composite figure = Area of the rectangle + area of the triangle
Area of the composite figure =
Thus, the area of the composite figure is
