Question:
To construct a unique rectangle, the minimum number of measurements required is
(a) 4
(b) 3
(c) 2
(d) 1
Solution:
(c) Since, in a rectangle, opposite sides are equal and parallel, so we need the measurement of only two adjacent sides, i.e. length and breadth.
Also, each angle measures 90°.
Hence, we require only two measurements to construct a unique rectangle.
