27 cm^2

Step-by-step explanation:

The surface area of this pyramid is given by this formula:

● Sa = area of the base + area of the sides *4

The faces are triangles.

The area of a triangle is:

● A = (b*h)/2

b and h are the base and the heigth

● A = (3*3)/2 = 9/2 = 4.5

The base is a square since all the sides are equal to each other.

The area of a square is:

● A'= a^2

a is the side

● A'= 3*2 = 9

● Sa = A' + 4*A

● Sa = 9 + 4×4.5

● Sa = 27 cm^2

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.
