Question

Find the area of triangle with sid 35cm, 54cm and 61 cm

Answer 1

HI DEAR,
here is ur answer.............................................
by Heron's formula we can find the  area of triangle......
s=(35+54+61)/2
  =150/2
   =75
so,
(area f triangle)^2=s(s-a)(s-b)(s-c)
                              =75(75-35)(75-54)(75-61)
                              =75(40)(21)(14)
                               =882000
so,
area of triangle=root 882000
                       =939.1cm.^2
HOPE IT HELPS UH.........................................
