aleksley [76]

Answer:

The length of the yard is $48\ ft$

Step-by-step explanation:

see the attached figure to better understand the problem

we know that

The perimeter of the yard required to be fenced is equal to

$P=(5x+8)+2(3x-1)+2(x-2)\\P=13x+2$

$P=106\ ft$

$106=13x+2$

solve for x

$13x=106-2$

$13x=104$

$x=104/13=8\ ft$

Find the length of the yard

$5x+8=5(8)+8=48\ ft$
