Areas
The area of a shape is the amount of space it occupies
<h3>Composite figure</h3>The figure (see attachment) is a composite figure, and the total area is the sum of the areas of each shape that makes up the complete figure
The shape has 6 equilateral triangles, each of which has an area of:
Where:
--- the length of each toothpick
The area of the rectangle is then represented as:
So, the total area of the figure is:
This gives
Substitute 6 for s
Hence, the total area of the figure is 139.20 square centimeters

Given:
Amplitude = 2
Midline = 5
Period of .
To find:
The cosine function.
Solution:
The general cosine function is:
...(i)
Where, |A| is amplitude, is period,
is phase shift and D is the mid line.
Period of function is . So,
Substituting in (i), we get
Therefore, the required cosine function is .
