Work Step by Step

The perimeter is the sum of the sides of the shape. P=a+b+c To find the third side a we isolate for a in the equation. a=P-b-c Given that P= 16x+3, b=5x-1 and c= 2x+5 we substitute it into the equation above. a= (16x+3)-(5x-1)-(2x+5) A= 16x+3-5x+1-2x-5 We combine like terms. A= 16x-5x-2x-5+3+1 A= 9x-1
