Answer:
[tex]6x+5[/tex]
Step-by-step explanation:
Given that:
Perimeter of the trapezoid = [tex]15x+11[/tex]
Shorter base = [tex]3x+4[/tex]
One leg = [tex]2x+3[/tex]
Second base = [tex]4x-1[/tex]
To find:
The length of fourth Side = ?
Solution:
Let us have a look at the perimeter of a trapezoid.
Perimeter = Sum of all the sides
Let the fourth side = [tex]y[/tex]
Using the formula and putting the given values:
[tex]15x+11=3x+4+2x+3+4x-1+y\\\Rightarrow 15x+11=9x+6+y\\\Rightarrow y = 15x-9x+11-6\\\Rightarrow y =6x+5[/tex]
Fourth side is: [tex]6x+5[/tex]
