Answer 1

Answer:

6

Step-by-step explanation:

area of parallelogram=base×height

=x×2x

144=2xsquare

root144=2x

12=2x

12÷2=x

x=6

Answer 2

Answer:6 root 2

Step-by-step explanation:

Given b= 2 h. (Where ‘b’ is the length of the base and ‘h’ is the length of the height.

Area of parallelogram= 144 sq.cm

Area of parallelogram= bh

144= (2h)(h)

144=2h²

72=h²

√72=h = 6√2
