Answer:

The perimeter in units of the model is $(86x+24)\ units$

Step-by-step explanation:

we know that

The perimeter of the figure is equal to the perimeter of the rectangle plus the  the length sides of the legs of the isosceles triangle

so

$P=2(17x+8)+2(21x+5)+2(5x-1)\\ \\P=(34x+16)+(42x+10)+(10x-2)\\ \\P=(86x+24)\ units$
