Answer 1

Answer:

68

Step-by-step explanation:

Area of a triangle=A+B+C

Area=25+26+17

Area=68

Answer 2

Answer:

204 cm square

Step-by-step explanation:Heron's Formula for the area of a triangle

s=perimeter,A=area of triangle, abc are the sides

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·*√174+2·(17·25)2+2·(17·26)2﹣254+2·(25·26)2﹣264

=204cm²
