In conclusion, the area of a triangle is calculated by multiplying half of the base length by the height length. Make sure the units of measurement are consistent before performing the calculation.

Therefore, the area of the triangle in the first case is 24 square cm and in the second case is 138 square cm.

For the second case, we first convert the measurements to cm: 2.3*** = 23 cm and 1.2*** = 12 cm. Then, using the formula Area = 0.5 * base * height, we find: Area = 0.5 * 23 cm * 12 cm = 138 square cm.

For the first case, the area of the triangle is calculated using the formula: Area = 0.5 * base * height. Substituting the given values, we get: Area = 0.5 * 8 cm * 6 cm = 24 square cm.
