Find the area of each triangle.

Find the area of each triangle. a = 2,b = 10, c = 11 (b) a = 4,b=8,c = 6 (c) a = 7, b = 12, c = 12

Solution

s=(a+b+c)/2

area =[s(s-a)(s-b)(s-c)]

a)

a =2 b =10 , c=11

s=(2+10+11)/2 =23/2

area =[(23/2)(23/2 -2)(23/2 -10)(23/2 -11)]

area =9.05

b)

a =4 b =8 , c=6

s=(4+8+6)/2 =9

area =[(9)(9 -4)(9 -8)(9 -6)]

area =11.62

c)

a =7 b =12 , c=12

s=(7+12+12)/2 =31/2

area =[(31/2)(31/2 -7)(31/2 -12)(31/2 -12)]

area =40.17
