Answer:
Calories for 19 is 75, 100
Servings for 19 is 12/3,
Oxygen for 20 is 16/15
Time (minute) for 20 is 4/4, 5/4
Step-by-step explanation:
width = w
length = w +2
perimeter = 2L + 2w
40 = 2(w+2) + 2w
40 = 2w+4 +2w
40 = 4w+4
36=4w
w=36/4 = 9
with = 9
length = 9+2 = 11
area = l x w = 9*11 = 99 square cm
Answer:
