• # question_answer The base of a parallelogram is twice its height. If the area of parallelogram is $162\,\,c{{m}^{2}},$then find the base. A) $9\,\,cm$                    B)  $18\,\,cm$C) $32\,\,cm$                  D)  $\text{50}\,\,cm$

$b=2h:\,\,A=b\times h=2{{h}^{2}}=162c{{m}^{2}}$ $\Rightarrow \,\,{{h}^{2}}=81\Rightarrow h=9\Rightarrow b=2h=18cm$
