Question

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

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 perimeter
s=perimeter÷2
