Question

The side of triangle are 17 cm ,25 cm and 26 cm respectively what is it's area.....​

Answer 1

Answer:

17 CM ,25 CM, 26 CM

A=$\sqrt{s(s-a)(s-b)(s-c)}$ where s = $\frac{a + b + c}{2}$

A=$\frac{1}{4}$$\sqrt{ -a^{4} +2(ab)^{2} +2(ac)^{2} -b^{4} +2(bc)^{2} -c^{4} }$

A =$\frac{1}{4}$$\sqrt{-17^{4} +2(17.25)^{2} +2(17.6)^{2} -25^{4} +2(25.26x^{2} -26^{4} }$

A =204cm²

This is the answer .Hope it helps you.
