Question

find the area of triangle whose sides are 120 150 170
using herons formula ​

Answer 1

Answer:

120 +150+170= 440

area = 440

Step-by-step explanation:

Answer 2

Formula: Area = root of (s-a)(s-b)(s-c)
a = 120
b = 150
c = 170

s = a+b+c/2
s= 120+150+170/2
s = 440/2 = 220

Area = root of (s-a)(s-b)(s-c)
Area = root of (220-120)(220-150)(220-170)
Area = root of 100 * 70 * 50
Area = root of 10*10 * 7*10 * 5*10

Taking the pairs of tens out of the root,
Area = (10*10) root of 7*5
Area = 100 root of 35

If you’re ok with ur answer in root form, that’s great. You can just stop here. But if you need the decimal form...
⬇️

Root of 35 when done by long division is approximated to a value of 5.92

So 100*5.92 = 592

Therefore, your answer is 100 root of 35 units or 592 units (Remember, approximate value here!).
Hope this helps you!
