Fencing material

Ailey bought 10 meters of wire fencing material to enclose her triangular flower garden. If the lengths of the sides of the triangular garden are 2 ½ meters, 3 ⅔ meters, 2 ⅙ meters, how long will the excess wire fencing material be?

Correct answer:

e =  1 23 = 5/3 m

Step-by-step explanation:

x=10 m a=221=2+21=22 2+1=25=2.5 m b=332=3+32=33 3+2=3113.6667 m c=261=2+61=62 6+1=6132.1667 m  o=a+b+c=2.5+3.6667+2.1667=3258.3333 m  e=xo=108.3333=35 m=132 m=1.6667 m
