Question

2 sides of a triangle each 5 meter less then twice the third side if the perimeter of the triangle 55 meter find the length of sides ​

Answer 1

${\boxed{\tt{Answer:}}}$

$\implies$ Here,two sides of triangle are equal Hence, It is an isosceles triangle.

Let the measure of one side be x and Others two be 2x-5

$\star$ Perimeter= Sum of All sides

Given Perimeter = 55 m

$\textbf{\underline{\underline{According\:to\:question:}}}$

$x + 2x - 5 + 2x - 5 = 55m$

Let's arrange it to make it easier.

$x + 2x + 2x - 5 - 5 = 55m$

Add constants and Variables accordingly

$5x - 10 = 55m$

$5x = 55 + 10$

$5x = 65$

$x = \frac{65}{5}$

$x = 13m$

Measures of One side :

13 cm

Putting Value for other side:

$2x - 5$

$(2 \times 13) - 5$

$26- 5$

$21m$

$\textbf{\underline{\underline{Verification :}}}$

$13 + 21 + 21 = 55$

$55 = 55$

Answer 2

Answer:13m
