Mark the correct alternative in the following: While measuring the side of an equilateral triangle an error of k% is made, the percentage error in its area is

Question

Philoid · Accepted Answer

we know that the area of a equilateral traiangle is =A =(√3/4)×a²

Where a= side of equilateral triangle

So by the formula of approximation of derivation, we get,

=2×k

=2k% ans
