Question

Find the area of the polygon with the given vertices NL-2.1), P3.1). Q(3.-1), R=2. -1

Answer 1

6

1) Plotting the figure

We have:

We have a quadrilateral

2)

So we have a rectangle FC = 1 and DC =2 So its area is 2 square unts

On the left side, we have a triangle whose height is BF 4 and its base is 2

So the area of the triangle is b*h/2 =4*2/2 = 4

So the total area is 6
