Answer: B
Step-by-step explanation: Length x Width = Area
8 feet x width = 96 sq ft
8w = 96
X 0 y was 30
at x 12 y is about 55
12-0 = 12
55-30 = 25
25/12 = 2.08 inches per year average
so answer should be D
<u>PERIMETER</u>
Answer:
Answer is 28 m
Step-by-step explanation:
Breadth= 2m
Length= 2X6m
= 12m
Perimeter of a rectangle = 2X (Length+ Breadth)
= 2X (2+12)
= 2X14
= 28m
<u>AREA</u>
Answer:
Answer is 24 m
Explanation:
Length= 12
Breadth= 2
Area of a rectangle= Length X Breadth
= 12X2
= 24 sq. m

Answer:
I'm sorry I don't know the equation, but she walks 3 mph.
Step-by-step explanation:
We know that the answer is asking for speed, which needs both distance and time, so we also need both. Which is where the 9 mph is used. 9 mph means its a difference. b means biking mph, w means walking mph, sooo ----->>> b=w+9, and the difference in the 1st equation is 36, which means the first equation is 4 times larger than the b=w+9, so she walked 48 miles, as well as walked 12 miles in 4 hours. Divide then distances by 4, and you get 12 miles and 3 miles in one hour. Or 12 mph & 3 mph, which fits into 12=3+9. So she walks 3 miles per hour.
