Question

A parking lot is constructed in the shape of a parallelogram. What is the area of the parking lot? (Unit = square ft.)

  1. 16800
  2. 24000
  3. 28000
  4. 20000

The correct answer is: 24000


    24000 sq ft
    We know that area of a parallelogram = base x height
    Given, base = 200 ft and height = 120 ft
    Area = 200 x 120 = 24000 sq ft

    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.
