Table 1 . Perimeter Formulas

Shape Formula Variables

Square P=4s s is the length of the side of the square.

Rectangle P=2L+2W L and W are the lengths of the rectangle's sides (length and width).

Triangle a+b+c a,b , and c are the side lengths.

30 + 20 + 16 + 5=  71  

30 + 30 + 16 + 16 = 92

Answer:

Perimeter is C. 100 cm.

Step-by-step explanation:

Perimeter is the length of the border of the shape. To find perimeter, find the length of all the walls and add them up. One wall is 20 cm, another is 5 cm, 30 cm, 16 cm, 4 cm, and the last one is 25. Add them up to get 100 cm.

I found length 25 cm and length 4 cm by doing 30-5=25 cm and 20-16=4 cm.
