Step-by-step explanation:
Area is found by mulitplying width and height.
in
The ratio is 0.5in : 1ft, so if you multiply that ratio to the answer, you should get the answer in feet.
in x
The ratio of the length to the width is 
.
The ratio of the sides will be the same for the scale and actual figures.
I took the L/W of the scale figure
and set it equal to the L/W of the actual figure.
Now we can solve for the unknown width.
Cross-multiplication gives us this,
Divide by 2.4 and simplify,
Hope that helps! :)

Answer:
Step-by-step explanation:
Let p be the number of trees Wangari plants, and h be the time she spends planting them in hours.
We have been given that Wangari plants trees at a constant rate of 12 trees every 3 hours.
Let us find number of trees planted in 1 hour by dividing 12 by 3.
We can represent this information as:
Therefore, the equation relates the number of trees (p) Wangari plants, and the time (h) she spends planting them in hours.
