Question

Find the missing values:

S. No.	Base	Height	Area of the parallelogram
a.	20 cm		246 cm2
b.		15 cm	154.5 cm2
c.		84 cm	48.72 cm2
d.	15.6cm		16.38 cm2

Answer 1

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.	Base	Height	Area of the parallelogram
a.	20 cm	12.3	246 cm2
b.	10.3cm	15 cm	154.5 cm2
c.	5.8cm	84 cm	48.72 cm2
d.	15.6cm	1.05	16.38 cm2
