| 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) \[6\,cm,\text{ }4.8\text{ }c{{m}^{2}}\]
Correct Answer: B
Solution :
(b): \[h=\sqrt{{{3.4}^{2}}-{{1.6}^{2}}}\] \[=\sqrt{(3.4+1.6)(3.4-1.6)}\] \[=3.0\,cm\] Area =\[\frac{1}{2}\times 3\times 3.2=4.8c{{m}^{2}}.\]
