Answer:
Perimeter of the rectangle=16 x
Step-by-step explanation:
Step 1: Determine the dimensions of the rectangle
Width=x
Length=7 x
But;
Step 2: Determine the perimeter of the rectangle
P=2(L+W)
where;
P=perimeter
L=length
W=width
In our case;
P=unknown
W=x
L=7 x
replacing;
2(x+7 x)=2 x+14 x
16 x
Perimeter of the rectangle=16 x
