We know that the area of parallelogram 

= base x height

(a) Here, base = 20 cm and area = 246 cm2

\Area of parallelogram = base x height

⇒ 246 = 20 x height

⇒ height = 246/20

= 12.3 cm

(b) Here, height = 15 cm and area = 154.5 cm2 

\ Area of parallelogram = base x height

⇒ 154.5 = base x 15

⇒ base = 154.5/15

= 10.3 cm

(c) Here, height = 8.4 cm and area = 48.72 cm2 

\ Area of parallelogram = base x height

⇒ 48.72 = base x 8.4

⇒ base =48.72/8.4

= 5.8 cm

(d) Here, base = 15.6 cm and area = 16.38 cm2 

\Area of parallelogram = base x height

⇒ 16.38 = 15.6 x height

⇒ height = 16.38/15.6

= 1.05 cm

Thus, the missing values are:

S. No.BaseHeightArea of the parallelogram
a.20 cm12.3246 cm
b.10.3cm15 cm154.5 cm2
c.5.8cm84 cm48.72 cm2
d.15.6cm1.0516.38 cm2
