Step-by-step explanation:

3)

The regular hexagon can be seen as consisting of 6 identical triangles, so its area is equal to six times the area of one triangle:

The area of one triangle can be written as:

where:

is the base of the triangle

is the height

Substituting,

And so, the area of the regular hexagon is:

4)

Here we have a complex figure consisting of several regular figures.

We observe that the figure consists of 2 parallelograms, on top and on bottom, so the total area of the figure is the sum of the areas of the two parallelograms:

where is the area of one parallelogram, which is given by

where:

b = 7 yd is the base of the parallelogram

h = 3 yd is the height of the parallelogram

Therefore, the area of the parallelogram is

And therefore, the area of the figure is:

b. x- 48 =120

step-by-step explanation:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
