The perimeter of the triangle( LMN) round to the nearest unit is 31 units

The perimeter of a triangle

The formula for calculating the perimeter of triangle LMN is expressed as:

Perimeter of LMN = LM + MN + LN

From the figure

LN = 12 units

LM = MN = √(3-(-3))²+(5-2)²

LM = MN = √9²+3²

LM = MN = √90

LM = MN = 9.49 units

The perimeter of triangle LMN =12 units + 2(9.49)

The perimeter of triangle LMN = 31 units

Hence the perimeter of the triangle( LMN) round to the nearest unit is 31 units
