105
100
97

Step-by-step explanation

Area of the first rectangle is LxW=5X11=55 inch square

Area of the second rectangle LxW=14x3=42 inch square

Area of one triangle bxh/2=(3x5)/2=15/2 inch square

Area of the other triangle bxh/2=(3x3)/2=9/2 inch square

Total AREAS

55+42+15/2+9/2=109 inch square

voila

0.817 and 0.175
