Atriangle has 3 sides that measure 5 1/4 feet, 2 5/6 feet, and 8 7/12 feet what is the perimeter of the triangle ?

Perimeter = add up the sides

P = 5 1/4 + 2 5/6 + 8 7/12

need to get a common denominator of 12

5 1/4*3/3 = 5 3/12

2 5/6*2/2 = 2 10/12

8 7/12

P = 5 3/12+ 2 10/12 + 8 7/12

P = (5+2+8)+(3+10+7)/12

P=15 (20/12)

P =15 + 1 8/12

P = 16 2/3 ft
