Answer:
60 cm^2
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:
[tex] \sqrt{s(s - a)(s - b)(s - c)} [/tex]
[tex] \sqrt{18(18 - 13)(18 - 13)(18 - 10)} [/tex]
[tex] \sqrt{18 \times 5 \times 5 \times 8} [/tex]
[tex] \sqrt{3600} [/tex]
[tex]60 \: {cm}^{2} [/tex]
Hope this helps ....
Good luck on your assignment...
