Solved Example on Boundary

Ques: A gardener wants to plant 4 plants per meter along the boundary of a garden, which is represented by the quadrilateral ABCD shown in the figure. Calculate the number of plants required.

    A. 75
    B. 80
    C. 70
    D. 60
    Correct Answer: B


    Step 1: Perimeter of the quadrilateral ABCD = Sum of the four sides of the quadrilateral.
    Step 2: = AB + BC + CD + DA
    Step 3: = 3 + 8 + 4 + 5 = 20 meters [Substitute AB = 3, BC = 8, CD = 4, and DA = 5 and simplify.]
    Step 4: The number of plants required = 20 × 4 = 80.
