1. The surface area of the prism is square units. All measurements in the image below are in units. (Input whole number only.)

A triangular prism is shown with 2 right triangular sides having legs 8 and 6 and hypotenuse 10. The length of the prism is 7.5


2. A solid is composed of squares and equilateral triangles. Its net is shown below:

A triangular prism and its net are shown. The net is three squares with side length 7 units. Attached above and below the middle square are equal sized triangles.

The area of each triangle is 21 square units. The surface area of the triangular prism is square units. (Input whole number only)


3. A polygon is shown:

A polygon MNOPQR is shown. The top vertex on the left is labeled M, and rest of the vertices are labeled clockwise starting from the top left vertex labeled, M. The side MN is parallel to side QR. The side MR is parallel to side PQ. The side MN is labeled as 3 units. The side QR is labeled as 9 units. The side MR is labeled as 3 units, and the side NO is labeled as 2 units.

The area of polygon MNOPQR = Area of a rectangle that is 9 square units + Area of a rectangle that is square units. (Input only whole numbers, such as 8.)


3. On a coordinate grid, the coordinates of vertices P and Q for Polygon PQRS are P(1, 3) and Q(−2, 3). What is the length of Side PQ of the polygon?
a
2 units
b
3 units
c
4 units
d
6 units


4. The length of a rectangle is shown below:

On a coordinate grid from negative 6 to positive 6 on the x-axis and on the y-axis, two points A and B are shown. The point A is on ordered pair 2, 1, and the point B is on ordered pair negative 4, 1. A straight line joins the points A and B.

If the area of the rectangle to be drawn is 18 square units, where should points C and D be located, if they lie vertically below the line that connects B and A, to make this rectangle? (1 point)

a
C(−4, −5), D(2, −5)
b
C(−4, −8), D(2, −8)
c
C(−4, −6), D(2, −6)
d
C(−4, −2), D(2, −2)
