If a=under root s(s-a)(s-b)(s-c) then the value of a, when a =3 b =4c = 5 and s =a+b+c by 2

6

Step-by-step explanation:

Here it's given that ,

Also ,

And we need to find out the value of A , when

So , on substituting the respective values to find s we have ,

Now let's find out A as ,

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

the correct answer would be:

220 centimeters

to get this you can use the pythagorean theorem
