The area of the blue parts of the plane comprises of four trapezoids,
from which each area can be calculated.
Response:
1) The drawings of the shapes are attached
3) The calculation for the area of each shape are;
4) Area of each shape is as follows;
- Shape 1; Area = 8.74 square units
- Shape 2; Area = 8.74 square units
- Shape 3; Area = 2.06 square units
- Shape 1; Area = 2.08 square units
5) Sum of all blue areas is 21.64 square units
<h3>Which method is used to break the blue parts?</h3>
The type of shape the blue parts break into are trapezoids
Where;
<em>a</em>, and <em>b</em> are the lengths of the parallel sides;
h = The height of the trapezoid
The coordinates of the four shapes are;
- Shape 1 Coordinates; (0.6, 0), (-1.6, 0), (-0.4, 4.6), and (1.2, 4.6)
1) Please find attached the drawing of shape 1 created with MS Excel.
2) The formula for the area trapezoid formed by shape 1 is;
3) The area of the shape is, A =
4) Area of shape 1 is <u>8.74 square units</u>
- Shape 2 Coordinates: (0.6, 0), (-1.6, 0), (0.4, -4.6), and (1.2, -4.6)
1) The drawing of shape 2 created with MS Excel is attached
2) The formula for the area trapezoid formed by shape 2 is;
3) The area of the shape 2 is, A =
4) Area of shape 2 is <u>8.74 square units</u>
- Shape 3 Coordinates: (4, 0), (4.6, 1.6), (5.5, 1.6), (5.7, 0)
1) The drawing of shape 3 created with MS Excel is attached
2) The formula for the area trapezoid formed by shape 2 is;
3) The area of the shape 3 is, A =
4) Area of shape 3 is <u>2.08 square units</u>
Coordinates of shape 4; (4, 0), (4.6, -1.6), (5.5, -1.6), (5.7, 0)
1) The drawing of shape 4 created with MS Excel is attached
2) The formula for the area trapezoid formed by shape 2 is;
3) The area of the shape 4 is, A =
4) Area of shape 4 is<u> 2.08 square units</u>
- 5) The sum of the area of the blue shapes = 2 × 8.74 + 2 × 2.08 = <u>21.64</u>
