• # question_answer Use the inform anon given in the diagram to find. (A) Height of the triangle (B) The area of the triangle. A)  $5\,cm,\text{ }6.8\,c{{m}^{2}}$        B)  $3\,cm,\text{ }4.8\text{ }c{{m}^{2}}$C)  $3\,cm,\text{ }6.8\text{ }c{{m}^{2}}$         D)  $6\,cm,\text{ }4.8\text{ }c{{m}^{2}}$

(b): $h=\sqrt{{{3.4}^{2}}-{{1.6}^{2}}}$ $=\sqrt{(3.4+1.6)(3.4-1.6)}$ $=3.0\,cm$ Area =$\frac{1}{2}\times 3\times 3.2=4.8c{{m}^{2}}.$
