Help me please, its mathwatch
mars1129 [50]

Answer:

<h2>60 cm^2</h2>

Solution,

Let ,

a = 13

b = 13

c= 10

then,

s = a + b + c /2

= 13 + 13 + 10 / 2

= 36/2

= 18

Now,

Area of triangle:

\sqrt{s(s - a)(s - b)(s - c)}

\sqrt{18(18 - 13)(18 - 13)(18 - 10)}

\sqrt{18 \times 5 \times 5 \times 8}

\sqrt{3600}

60 \:  {cm}^{2}

Hope this helps ....

Good luck on your assignment...
