Derive a formula to find the perimeter of an isosceles triangle in which one of the equal

Scorpion4ik [409]

Given :

Length of one of the equal sides of an isosceles triangle = 3x+2

Then, length of the other equal side will also be = 3x+2

Length of the unequal side of this isosceles triangle = 14

Formula for finding the perimeter of an isosceles triangle :

$= \tt side + side + side$

A formula for finding the perimeter of this isosceles triangle :

$= \tt3x + 2 + 3x + 2 + 14$

Bringing all like terms together we get :

$=\tt 3x + 3x + 2 + 2 + 14$

$= \tt6x + 4 + 14$

$\color{plum}\tt = 6x + 18$

Thus, the formula = 6x+18

Therefore, a formula to find the perimeter of this isosceles triangle = <u>6x+18</u>
