Question

Find the missing values:

So No	Base	Height	Area of parallelogram
a.	20 cm	-	246 cm2
b.	-	15 cm	154.5 cm2
c.	-	8.4 cm	48.72 cm2
d.	15.6 cm	-	16.38 cm2

Answer 1

Area of parallelogram = Base × Height

(a) b = 20 cm

h = ?

Area = 246 cm²

20 × h = 246

Therefore, the height of such parallelogram is 12.3 cm.

(b) b = ?

h = 15 cm

Area = 154.5 cm²

b × 15 = 154.5

b = 10.3 cm

Therefore, the base of such parallelogram is 10.3 cm.

(c) b = ?

h = 8.4 cm

Area = 48.72 cm²

b × 8.4 = 48.72

Therefore, the base of such parallelogram is 5.8 cm.

(d) b = 15.6 cm

h = ?

Area = 16.38 cm²

15.6 × h = 16.38

Therefore, the height of such parallelogram is 1.05 cm.
