Area of parallelogram: \[ \text{Area} = \text{Base} \times \text{Height} \]
Let height \(= h\)
Base \(= 2h\)
\[ 144 = 2h \times h \]
\[ 144 = 2h^2 \] \[ h^2 = 72 \] \[ h = \sqrt{72} \] \[ h = \sqrt{36 \times 2} \] \[ h = 6\sqrt{2} \]
Therefore, height = \[ 6\sqrt{2}\text{ cm} \]
সামান্তরিকের ক্ষেত্রফল: \[ \text{Area} = \text{Base} \times \text{Height} \]
ধরি উচ্চতা \(= h\)
ভূমি \(= 2h\)
\[ 144 = 2h \times h \]
\[ 144 = 2h^2 \] \[ h^2 = 72 \] \[ h = \sqrt{72} \] \[ h = \sqrt{36 \times 2} \] \[ h = 6\sqrt{2} \]
অতএব উচ্চতা = \[ 6\sqrt{2}\text{ cm} \]
