Answer:
Step-by-step explanation:
1. Area of the composite figure = Area of the sector + Area of rectangle
Area of sector = (θ/ 360) x
From the figure,
θ = 30, and r = 65
Area of sector = x
x 65 x 65
= 1 1065.55
Area of rectangle = length x width
= 65 x 4
= 260
Area of the composite figure = 1 1065.55 + 260
= 11325.55
Area of the composite figure is 11326 .
