Answer:
the answer for this question is 15/14
to find area the formula is area = l×b
here length is 1 1/4 and breadth is 3/4 so l×b = 1 1/4=5/4 so 5/4×3/4=15/14
2) 
is a rhombus (a parallelogram with perpendicular diagonals is a rhombus)
3) 
bisects 
(diagonals of a rhombus bisect the angles from which they are drawn)
46 and 19. 46 x 19 = 874 and 46 - 19 = 27
