Question

find area of triiangle whose one side is 91 another is 98 and third is 105​

Answer 1

Answer:

Area of triangle is 1/2×91×98=4459

Answer 2

Answer:

4116m2

Step-by-step explanation:

Here, a = 91 m, b = 98 m and c =105 m

Therefore, S=91+98+1052=147

Area = S(S−a)(S−b)(S−c)−−−−−−−−−−−−−−−−−−√

= 147(147−91)(147−98)(147−105)−−−−−−−−−−−−−−−−−−−−−−−−−−−−√

= 147×56×49×42−−−−−−−−−−−−−−−√

= 49×3×7×2×2×2×49×7×3×2−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√

= 49×3×2×2×7 = 4116 m2
