Question

Q.-5) (a) Length of the fence of a trapezium shaped field KLMN is 120 cm. If KN = 40 cm, LM = 48 cm and MN = 17 cm. Side KL is perpendicular to the parallel sides KN and LM. Find the area of this field.
(b) Find the height of cylinder whose volume is 15.4 m3 and diameter of the base is 140 cm.​

Answer 1

Answer:

48+17+40+x=120

x=15 m.

Area =21 (sum of parallel sides) × height

=21(48+40)×15

=660 m2.
