Question

the perimeter of a triangle is 67 CM if its two sides measure 23 cm and 12 CM respectively find the third side​

Answer 1

Answer:

given

total perimeter of a triangle=67cm

fist side of triangle=23 cm

second side of triangle=12cm

so,

perimeter of triangle =AB+BC+CA

67=23+12+x

67=35+x

x=67-35

x=32

Answer 2

Answer:

Step-by-step explanation:

P = 67

a=23

b=12

c=?

P =a +b+c

67= 23+12+c

67 = 35 +c

c=67/35

c= 1.914cm
