  1. The graph of the linear equation 3x + 4y = 24 is a straight line intersecting x-axis and y-axis at the points A and B respectively.
    P(2, 0) and Q(0,(3/2)) are two points on the sides OA and OB respectively of ∆OAB, where O is the origin of the co-ordinate system. Given that AB = 10 cm, then PQ =
    1. 20 cm
    2. 2.5 cm
    3. 40 cm
    4. 5 cm
Correct Option: B

OP = 2

OQ =

∴ PQ = √OP² + OQ²
= √ 2² +
