Find the missing elements of the following parallelograms based on the information provided.

a) Area =121.5 m², base =16.2m, height =?b) Area =395cm², height =12.5 cm, base =?
c) Area =351 m², base =15.6 m, height =?
d) Area 4440 cm², height =74 cm, base =?

Solution:

Area of parallelogram = A = base x height  = b x h

a) A = 121.5  sq m, b = 16.2 m, h = ?   

Ans h = $\frac{A}{b} = 1\frac{21.5}{16.2}$ = 7.5 m

b) A = 395 sq cm;   h = 12.5 cm, b = ? 

Ans   b =$\frac{A}{h} =\frac{395}{12.5}$ = 31.6 cm

c) A = 351 sq m;  b = 15.6 m,   h = ? 

Ans h = $\frac{A}{b} = \frac{351}{15.6}$ = 22.5 m

d) A = 4440 sq cm;  h = 74 cm, b = ? 

Ans  b = $\frac{A}{h} = \frac{4440}{74}$ = 60 cm
