Slot – 3 – Quantitative Aptitude – Geometry – In a trapezium ABCD, AB is parallel to DC
Q. In a trapezium ABCD, AB is parallel to DC, BC is perpendicular to DC and angle BAD=45 degree. If DC=5 cm, BC=4 cm, the area of the trapezium in sq cm is? Answer: 28
Solutions:
In triangle DAE , angle DAE = 45 so DE = AE = 4
Thus AB = 5+4 =9
So area of ABCD = ½ (5+9)*4 =28
