To find:

THE AREA OF A TRIANGLE WITH SIDES 28M, 15M AND 41M.

Calculation:

Let semi-perimeter be s ;

s =  \dfrac{28 + 15 + 41}{2}  =  \dfrac{84}{2}  = 42 \: m

Now , applying Heron's formula:

area =  \sqrt{s(s - 28)(s - 15)(s - 41)}

 =  > area =  \sqrt{42(42- 28)(42 - 15)(42 - 41)}

 =  > area =  \sqrt{42 \times 14 \times 27 \times 1}

 =  > area =  \sqrt{14 \times 3 \times 14 \times  {3}^{3}  }

 =  > area =  \sqrt{ {14}^{2}  \times {3}^{4}  }

 =  > area =  14 \times  {3}^{2}

 =  > area =  14 \times  9

 =  > area =  126  \:  {m}^{2}

So, final answer is:

 \boxed{ \bf{ area =  126  \:  {m}^{2} }}
