Answer:

Step-by-step explanation:

Area of triangle = [tex]\frac{1}{2}*base*height[/tex]

                           [tex]= \frac{1}{2}*9*11\\\\=\frac{99}{2}\\\\= 49.5 yd^{2}[/tex]

Area of rectangle =length * width

                             = 11* 20

                             = 220 sq.yd

Area of the shaded region = area of rectangle - area of triangle

                                            = 220 - 49.5

                                            = 170.50 sq.yd

Answer:

170.5 yd^2

Step-by-step explanation:

To calculate the area of the whole rectangle (green shaded + unshaded) multiply width and length

11 × 20 = 220 yd^2

The area of the triangle (unshaded area) is calculated by multiplying height to the base and that divided by two

11 × 9 ÷ 2 = 49.5 yd^2 now to find the area of the green shaded part we subtract 49.5 from the whole area

220 - 49.5 = 170.5 yd^2
