Question

the side of a traingleis 8 cm 15 cm and 17 cm find the area ​

Answer 1

Answer:

A=s(s﹣a)(s﹣b)(s﹣c)

s=a+b+c

2

Solving forA

A=1

4﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·﹣84+2·(8·15)2+2·(8·17)2﹣154+2·(15·17)2﹣174=60cm²

Answer 2

Using the formulas,

A=

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

s=a+b+c

2

Solving forA

A=1

4﹣a4+2(ab)2+2(ac)2﹣b4+2(bc)2﹣c4=1

4·﹣84+2·(8·15)2+2·(8·17)2﹣154+2·(15·17)2﹣174=60cm²
