Answer is 28 inches.
A square has equal sides and to find the perimeter, you add all the sides.
7 x 4 = 28
No because the perimeter of a rectangle is L×W or (2L+2W) , but the perimeter of a square is S×S×S×S so there is a difference between the two.
Answer:
1 2/3
Step-by-step explanation:
Perimeter is the outside of the shape all you have to do is add up the outside border of the shape.
1. 1/6+1/6=2/6
2. 2/3+2/3=4/3
3. 4/3 + 2/6= 1 2/3
