Answer:
Area : 114.25 in^2
Perimeter : 47.7 in
Step-by-step explanation:
In this problem when finding the perimeter you have a normal triangle and a semi-circle. so you add the 2 sides of the triangle and find the circumference of a semi-circle with a radius of 5.
17 + 15 + {(3.14)[2(5)]}/2 =
32 + {(3.14)[10]}/2 =
32 + 31.4/2 =
32 + 15.7 =
47.7
When finding the are you have to make the shapes as easy as possible. In this case you divide it to be triangle and semi-circle. Then add the 2 areas together.
[15(10)]/2 + {(3.14)[(5)^2]}/2
150/2 + {(3.14)[25]}/2
75 + 78.5/2
75 + 39.25
114.25
Because the distance to both chords are the same (5.70) and both chords are 90 degrees from the 5.70 line, both chords are identical.
Chord AB = 5, so chord CD is also 5.
The area of the rectangle is the length times the width.
Now let's convert all these fractions into improper fractions to make it easier to multiply
Now let's multiply them for the area = square feet.
