Answer:
Volume is 21
Explanation
Base length is 4.5
Widgth is 3.5
and height is 4 (I can't tell if its 2 because picture is blurry)
V=lwh/3=4.5·3.5·4= 21
N= x+15 where n = nina, x = the amount hiked together and the 15 is how much she already walked.
You subtract 15.50 from 47.50
then you will get your answer it is 31
21,800,000 rounded to the nearest million = 22,000,000
Answer: 54 square feet
Step-by-step explanation:
To find perimeter of a rectangle we must use the formula l+l+w+w=p where l and w represent width and length
Since we know length and width is x=12 just substitute so
15+15+12+12=54 so 54 is the perimeter
