find area of triangle whose side are 120,170,250
Answers
Step-by-step explanation:
s=120+170+250/2=620/2=310
area=√320×(320-120)×(320-170)×(320-250)
=√320×200×150×140
=√2×2×80×2×5×5×2×3×5×5×2×2×7×5×2
=2×2×2×2×5×5×5×7×80
=1120000
Answer:
to find area when sides are given use herons formula
Area = √s(s-a)(s-b)(s-c)
=. √415(415-120)(415-170)(415-250)
=. √415 ( 295 ). ( 245 ) ( 165 )
=. √5 X 83 X 2 X 59 X 5 X 7 X 7
=. √ 83 X 59 X 5² X 7 ²
=. 5 X 7 √ 83 X 59
=. 35 √ 4897
=. 35 √ 69²
=. 35 X 69
=. 2415m²
Step-by-step explanation:
s = a+b+c/2
s = 120 + 170 + 250 /2
s =. 415
Afterwards herons formula apply find LCM factors of all then square root and finall answer
in m² all the times
I have solved it correctly
