Question

find the area of triangle whose sides are 11m ,60 m and 61 m

Answer 1

By using Herons formula u can find the area of the triangle
Area of the triangle=√s(s-a)(s-b)(s-c) 
    Let  a=11m           
  b=60m           
  c=61m                 
   s=(a+b+c)÷2                     
 =(11+60+61)÷2                ∴s=66m                     
  =132÷2  = 66m
As I said  Area =√s(s-a)(s-b)(s-c)                       
=√66(66-11)(66-60)(66-61)                     
  =√66×55×6×5                 
 We can take the common factors outside                        
 =√6×11×5×11×6×5               
  By removing the roots we will get                       
  =6×11×5                       
  =330m² Pls check before doing

You can also find 's' if you are given the perimeters=perimeter÷2
