Answer 1

⏩sorry but u not explain ur question properly...but by using this formula u will get the area of triangle...

area of triangle = 1/2 × base × hieght..

❣hope it helps u thanku:-)❣

Answer 2

Step-by-step explanation:

we know that the formula of area of triangle is :

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

a = 9 cm

b = 10 cm

c = 17 cm

Semi perimeter, s = 9 + 10 + 17 / 2

= 36 / 2

= 18 cm

Now,

We apply -

$= \sqrt{18(18 - 9)(18 - 10)(18 - 17)}$

$= \sqrt{18 \times 9 \times 8 \times 1}$

$= 36cm {}^{2}$

Hence the area of triangle is 36cm^2

Hope it helps
