By Consumer Dummies

If you take a look around, you can see squares and rectangles everywhere. In fact, they’re so popular that you’ll even find them on the Mathematics Knowledge subtest on the ASVAB.

These questions may ask you to find the area or perimeter of a square or rectangle, so you should memorize the appropriate formulas.

Practice questions

  1. Find the area:

    asvab-find-area

    A. 72 sq. ft.
    B. 60 sq. ft.
    C. 18 sq. ft.
    D. None of the above

  2. Find the perimeter:

    asvab-perimeter

    A. 60 ft.
    B. 100 ft.
    C. 37.5 ft.
    D. 75 ft.
