Question

#6
6.8m
21.1m
area:

Explanation:

Step1: Identify the triangle type (assuming it's a right triangle)

If we assume the triangle is a right triangle with legs \( a = 6.8\,\text{m} \) and \( b = 21.1\,\text{m} \), the area formula for a right triangle is \( A=\frac{1}{2}ab \).

Step2: Substitute values into the formula

Substitute \( a = 6.8 \) and \( b = 21.1 \) into \( A=\frac{1}{2}ab \):
\( A=\frac{1}{2}\times6.8\times21.1 \)
First, calculate \( 6.8\times21.1 = 143.48 \)
Then, \( \frac{1}{2}\times143.48 = 71.74 \)

Answer:

The area of the triangle is \( 71.74\,\text{square meters} \) (assuming it is a right - triangle with the given sides as legs). If the triangle is not a right - triangle, more information (such as height corresponding to a base) is needed to calculate the area accurately.
