Question

3 Find the missing elements of the following parallelograms based on the
information provided.
(a) Area = 121.5 m2, base = 16.2 m, height = ?
(b) Area = 395 cm2, height = 12.5 cm, base = ?
(c) Area = 351 m2, base = 15.6 m, height = ?
(d) Area = 4440 cm2, height = 74 cm, base = ?​

Answer 1

a) area of parallelogram = bh

121.5 = 16.2h

h=121.5/16.2

h=7.5

b) 395 = 12.5b

b=395/12.5

b=31.6

c) 315 = 15.6h

h = 315/15.6

h =20.192

d) 4440=74b

b = 4440/74

b = 60

hope this answer may help you
