Question

the slides of a triangle are x, (x+1) and 13 cm. if its perimeter is 56cm.then find the value of x​

Answer 1

Answer:

✮Formula used:

Perimeter of the triangle= a+b+c

✮Solution:

x+x+1+13=56

$⇒2x + 14 = 56$

$⇒2x = 56 - 14$

$⇒x = \frac{42}{2}$

$⇒x = 21$

Therefore, The value of x is 21.

Answer 2

Given question -:

the slides of a triangle are x, (x+1) and 13 cm. if its perimeter is 56cm.then find the value of x

let us first understand the meaning of perimetre

perimeter = the boundary of a closed plane figure.

let's try to solve the question

$perimeter \: of \: triangle \: = a + b + c$

so

$x + x + 1 + 13 = 56$

$2x + 14 = 56$

$2x = 56 - 14$

$2x = 42$

$x = 21$

Now value of x

$x = 21$

$x + 1 = 21 + 1 = 22$

Hope this will help you
