1. Draw VR....this creates triangle VMR and rectangle VRDE
Let VR be the base of triangle VMR = 6 units and the height drawn from M to the base = 3 units
So...the area of this triangle is (1/2)base* height = (1/2) 6 *3 = (1/2) 18 =
9 units^2 (1)
And rectangle VRDE has area VR * VE = 6 * 5 = 30 units^2 (2)
So.....adding (1) and (2) gives the total area of 39 units^2
2. Connect ( 2, 1) and (3, -3)....this creates a rectangle with vertices (2,1) , (3, -3), (-5, -5)
and (-6, -1)
The distance from (2,1) to (3, -3) forms one side of this rectangle = √17 units
The distance from (-6, -1) to (2,1) forms the other side of this rectangle = 2√17 units
So....the area of this rectangle is √17 * 2√17 = 2 * 17 = 34 units^2 (1)
Connect (2, 1) and (3, 1)......this forms a triangle at the bottom right with vertices (2,1), (3,1)
and (3, -3)
The base of this triangle is (2,1) to (3,1) = 1 unit
And the height of this triangle is (3, 1) to (3, -3) = 4 units
So...the area of this triangle is (1/2) (1) (4) = 2 units^2 (2)
Connect (2,3) and (3,3)....this creates a rectangle with vertices (2,3) (3,3), (2,1) and (3,1)
The height of this rectangle is (3,1) to (3, 3) = 2 units
And the widthof this rectangle is from (2,1) to (3,1) = 1 unit
So...the area of the rectangle is 2 * 1 = 2 units^2 (3)
Finally....we have a triangle with the vertices (2,3), (3,3) and (2,7)
The base of this triangle is from (2,3) to (3,3) = 1 unit
And the height of this triangle is from (2,3) to (2,7) = 4 units
So....the area of this triangle is (1/2) (1) (4) = 2 units^2 (4)
So the total area = (1) + (2) + (3) + (4) = [34 + 2 + 2 + 2] =
40 units^2
