Triangle lmn has sides measuring 7 meters and 6 meters and a perimeter of 16 meters.

what is the area of triangle lmn? round to the nearest square meter.
3 square meters
9 square meters
28 square meters
34 square meters

 The area of the triangle is 9 m².

Step-by-step explanation:  Given that the measures of two sides of triangle LMN are 7 meters and 6 meters.

We are to find the area of the triangle if its perimeter is 16 meters.

Let, a, b and c represents the lengths of three sides of a triangle.

Then, the area of the triangle will be

In ΔLMN,

a = 7 m and b = 6 meters.

The perimeter of ΔLMN is 16 meters. So, we have

This implies that

Therefore, the area of ΔLMN is

Thus, the area of the triangle is 9 m².
