Question

help me please, its mathwatch

Answer 1

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:

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

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

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

$\sqrt{3600}$

$60 \: {cm}^{2}$

Hope this helps ....

Good luck on your assignment...
