Answer:
Perimeter=8x +34
Step-by-step explanation:
The only missing side if the shape is the slant side .
To determine the slant height we'll use the right angle rule and take the slant side as the hypotenuse.
For the slant side, let it be y
(2(x+7) -(x+5 +x-3))² +((2x+5)-(2x))²= y²
(2x+14-2x-2)² + (5)² = y²
(12)² +25 = y²
144+25 = y²
169= y²
Y= √169
Y= 13
Now the perimeter= 2(x+7)+(2x+5)+(x-3)+(2x)+(x+5)+13
Perimeter= 2x+14+2x+5+x-3+2x+x+5+13
Perimeter=8x +34
