If one side of a rhombus has end points (4, 5) and (1, 1), then the maximum area of the rhombus is
A)50 sq units
B) 25 sq units
C) 30 sq units
D) 20 sq units
Correct Answer:
B
Solution :
From the figure, Area of rhombus \[=2\times \](area of\[\Delta ABD\]) \[=2\times \frac{1}{2}\times 5\times 5\times \sin \theta =25\sin \theta \] Hence, maximum area is 25 sq units (when \[\sin \theta =1\]).
