Slot -2 – Quantitative Aptitude – Geometry – Mensuration – A parallelogram ABCD has area 48 sqcm

A parallelogram ABCD has area 48 sqcm. If the length of CD is 8 cm and that of AD is s cm, then which one of the following is necessarily true?

a) 5≤s≤7
b) s≤6
c) s≥6
d) s≠6

Answer: c) s≥6

Solution: 1

Solution: As the area of ABCD = 48=s×h ————1)
In right-angled triangle CKD, DK ≤ CD ( CD is hypotenuses )
So h ≤8
Thus s ≥6——-(from eq 1)
