Question

A triangular section of land has side length of 6km, 4km and 3km. What is the area of the region of land?

Answer 1

We have

First we will calculate the semi perimeter

`s=(a+b+c)/(2)`

where a,b, and c is the length of the sides of a triangle

a=6km

b=4km

c=3km

we substitute the values

`s=(6+4+3)/(2)=6.5`

Then we will use the next formula to find the area

`A=\sqrt[]{s(s-a)(s-b)(s-c)}`

then we substitute the values
