Question

if a b and c are the sides of a triangle then the area of triangle when each of the side is doubled will be​

Answer 1

So , sides of a triangle are a,b and c

When it is doubled then sides will be 2a,2b and 2c

So, s = a+b+c/2

s = 2a+2b+2c/2

s = a+b+c

So By Herons formula

s = √s(s-a)(s-b)(s-c)

And so on hint is given try your own
