Answer 1

Answer:

Using the formulas

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·﹣304+2·(30·25)2+2·(30·15)2﹣254+2·(25·15)2﹣154≈187.08287cm²

Answer 2

Step-by-step explanation:

Using the formulas

A=s(sa)(s - b)(s - c)

s=a+b+c2

Solving forA

A=1

4a4+2(ab)2+2(ac)2 - b4+2(bc)2 - c4=1

4.-304+2 (30.-25)2+2-(30-15)2 - 254+2 (25-15)2 - 154-187.08287cm²
