The correct option is B 2
A rectangle is parallelogram where its opposite sides are equal and all angles equal to 90∘.
So, by knowing the measure of a set of its adjacent sides, we will get the measurement of all of its sides and all angles of a rectangle is equal to 90∘. By knowing all sides and angles we can construct an unique rectangle.
Hence, the minimum number of measurements required for the construction of a rectangle is 2.
