Sides of a triangle are 13 cm.14cm.and 15cm.respectively.calculate the area of triangle.
Answer/Solution
84
Steps/Work
let a=13cm, b=14cm.and c=15 cm.
s=1/2(13+14+15)=21,(s-a)=8,(s-b)=7 and (s-c)=6
Area=√21*8*7*6=84 sq.cm
Answer C
s=1/2(13+14+15)=21,(s-a)=8,(s-b)=7 and (s-c)=6
Area=√21*8*7*6=84 sq.cm
Answer C
