  • Q #2: The length of a rectangle is 3 units greater than its width. Which expression would correctly represent the perimeter of the rectangle?

    A. 2W+2[W+3]

    B. W+W+3

    C. W[W+3]

    D. 2W+2[3W]

    Answer Explanation

    Let width of the rectangle be W. We are told that length, L is 3 units greater than width. Then,

    L=W+3

    And perimeter of the rectangle is given by the relation, P=2(L+W]=2L+2W

    In place of L substitute W+3. Thus,

    P=2[W+3]+2W

  • Q #3: A homeowner has hired two people to mow his lawn. If person A is able to mow the lawn in 2 hr by herself and person B is able to mow in lawn in 3 hr by himself. Which of the following is the amount of time it would take for both person A and B to mow the lawn together?

    A. 5 hours

    B. 2.5 hours

    C. 1.2 hours

    D. 1 hours

    Answer Explanation

    We know that the two people work on the same work but the time to complete the work differs. Thus, the rate of doing the work for each person is as follows:

    Rate of work for person A = 1 /2 work per hr

    Rate of work for person B=1/3 work per hour

    If person A and B work together, the time of doing the same work will be less than the fastest person A. Thus, we combine the two rates of A and B

    We have 1 work and time to complete by both A and B becomes
