The total area of the figure is 139.20 square centimeters
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

Recall your d = rt, distance = rate * time
so... hmm if the plane has a still air speed of say "r", when it's going with the wind, is not really going "r" fast, is going "r + 40 ", because the wind is adding 40mph to its speed, is really moving.
and when the plane is going against the wind, is not really going "r" fast either, is going " r - 40 ", because the wind is eroding speed from it.
now, it went 2240 miles for say "t" hours, and it did 1920 miles for the same length of time, "t" hours.
and surely you know how much that is.
