Question

Help me please, its mathwatch

Answer 1

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:

`√(s(s - a)(s - b)(s - c))`

`√(18(18 - 13)(18 - 13)(18 - 10))`

`√(18 * 5 * 5 * 8)`

`√(3600)`

`60 \: {cm}^(2)`

Hope this helps ....

Good luck on your assignment...
