From the given graph ,
DEVR is a rectangle
Now we find area of rectange DEVR
Area of rectangle = base * height
In rectangle DEVR , Base = 5 units and height =6 units
Area of the rectangle DEVR = 5 * 6 = 30
Now we find area of triangle MVR
Area of triangle = [tex] \frac{1}{2} [/tex] * base * height
Triangle has base 6 units and height 3 units
Area of triangle MVR = [tex] \frac{1}{2} [/tex] * 6 * 3 = 9
Area of this polygon = Area of the rectangle DEVR + area of triangle MVR
= 30 + 9 = 39 square units
