Find the value of x for the given triangle or rectangle

Perimeter 34 in.

Short Answer

Expert verified

Length of side of triangle isx=9 inches.

Step by step solution

01

Step-1- Using perimeter of triangle formula

We know Perimeter of triangle is equal to sum of all the three sides of triangle.

Therefore,

Perimeter of triangle = sum of all sides of triangle

02

Step-2-Calculating side of triangle 

On substituting values, we get

34=x+11+14x+25=34
03

Step-3-Solving for value of x

Subtracting 25on both sides, we get

x+25-25=34-25x=34-25x=9

Therefore,

Length of third side =x=9inch.
