Answer:
The area of the figure is 49.12ft² (nearest hundredth)
Step-by-step explanation:
The area of the figure is the sum of the areas of the right triangle and semi circle that make up the figure.
Note that the radius of a circle is twice its diameter
That means, the radius of the semi-circle is 4 feet
Area of the triangle = 1/2 x Base X Height = 1/2 x 6 ft x 8 ft =24 ft²
Area of the semi circle = 1/2 πr² = 1/2 x 3.14 x 4² = 25.12 ft²
Hence, the area of the figure is:
24 ft² + 25.12 ft² = 49.12 ft²
For the first 6 trips she walked 3.2 kilometers and for the next 6 she made another 3.2 which would be 6.4 kilometers for 12 trips now she made 3 more trips which is half of the amount she originally did so it would be half of the distance also so 3.2 divided by 2 is 1.6 kilometers so for the last 3 trips she walked 1.6 kilometers. now add up all the distance she walked so 6.4 kilometers for the 12 trips plus the 1.6 for the other 3 trips is 8 kilometers in total. she walked 8 kilometers after 15 trips.
