Question

find the missing value:
​

Answer 1

a) area of parallelogram =b x h

246 =20 x h

h =246/20

h =12.3cm


b) area of parallelogram =b x h

154.5 =b x 15

b =154.5/15

b =10.3cm

c) area of parallelogram =b x h
48.72=b x 8.4
b=48.72/8.4
b=5.8cm

d) area of parallelogram =b x h
16.38=15.6xh
h =16.38/15.6
h =1.05cm

Answer 2

(a) BH = A or, 20H = 246 or, H = 246/20 = 12.3 cm

(b) BH = A or, 15B = 154.5 or, B = 154.5/5 = 30.9 cm

(c) 8.4(B) = 48.72 or, B = 48.72/8.4 = 5.8 cm

(d) 15.6(H) = 16.38 or, H = 16.38/15.6 = 1.05 cm
