First draw rectangle with and cm.
Next draw point in such a way that and point in such a way that .
Now you can draw the pentagon .
This pentagon has two angles of , one angle of and an angle of .
and are parallel and .
, and cm.
To be able to draw this figure it is smart to first calculate the height of the trapezium.
That height is cm.
The trapezium has two angles of approximately and two angles of approximately.
and .
and .
The width of the loft floor is m.
The length of the loft floor is m.
Therefore the area of the floor is m2.
Besides you see the (right) trapezium.
The edge denoted by m has an exact length of .
The longest edge of the trapezium is m.
Besides two right angles there is an angle of approximately and an angle of approximately .
When is the height of the tree, then cm.
So cm. Therefore it is only a small tree of approximately m.
When is the distance to the Statue of Liberty: . This means cm, that is m.
.
Take , then . So . This gives .
