Question

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

  1. 14
  2. 28
  3. 49
  4. 16

The correct answer is: 28


    28 sq cm
    We know that area of a parallelogram = base x height
    Given, base = 7 cm and height = 4 cm.
    Area = 7 x 4 = 28 sq 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.

    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.

    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.
