Sherice plays the bass in a garage band. Sherice’s parents let her and her friends use a section of their garage in the shape of a parallelogram for rehearsals. How much space in square feet does Sherice’s band have to practice in?

The wall in is to be painted. If one can of paint covers 110 square feet, how many cans of paint will be needed if only one coat of paint is applied?

A 7-foot by 3-foot doorway is to be cut into the trapezoid shaped wall shown. What is the area of the wall, without the doorway? (Unit = square ft.)

The triangular swimming pool shown is surrounded by a concrete patio. Find the area of the patio. Round to the nearest tenth if necessary.  (Unit = square m.)

Find the area of the following parallelogram: (Unit = square cm.)

A parallelogram can be thought of as a combination of 2 triangles of equal area .
Area of 1 triangle = ½ x base x height.
Area of 2 triangles = 2x ½ x base x height = base x height.

A parallelogram can be thought of as a combination of 2 triangles of equal area .
Area of 1 triangle = ½ x base x height.
Area of 2 triangles = 2x ½ x base x height = base x height.

Find AB, if the area of the triangle ABC is 48 square m. and the height CD is 12 m.  (Unit = m)

Find the area of the triangle given below: (Unit = square cm)

Identify the shape that will be angled cross-section of a rectangular pyramid.

The plane cuts the pyramid at an angle which is not parallel to the base of the cone, this is the reason why we are getting a rectangle but with a length : breadth ratio different than that of the base.

Name the shape that would result from slicing a rectangular pyramid parallel to the base

Since the pyramid is rectangular, this means that the base of the pyramid is a rectangle. Therefore, if we slice it parallel to the base, we’ll get a cross section which will look like the base of the pyramid, i.e., a rectangle.

Describe the cross section.

From the given figure, we can observe that the plane cuts the prism making an angle of 0 degrees with the base of the prism. Thus, we’ll get a cross section which will be similar to the base of the prism, i.e., a triangle.

Describe the cross section.

The plane cuts the cone at an angle which is not parallel to the base of the cone, this is the reason why we are getting an oval. If the plane did cut the cone making 0 degrees with the base of the cone, then we would have got a circle.

Find the number of faces the following prism has.

From the given figure, we can see that there are a total of 7 faces of the prism. 5 of them re at the sides ( 3 of which are visible from the front and 2 of which are visible from the back) and 2 of them are at the top and bottom respectively.
