Plss can someone help me with this thank you

Step-by-step explanation:

Area of triangle =

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

which is .75

then you will have to divide 1.5 by .75

which is 2

no you have to divide

0.02
