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.
Solution:
Perimeter is the sum of the figure's sides.
<u>Note that:</u>
- 10 + 10 + 4 + 10 + 4 + 10 + 10 + 30 = Perimeter of figure
<u>Simplify the expression:</u>
- 5(10) + 2(4) + 30 = Perimeter of figure
- => 50 + 8 + 30 = Perimeter of figure
- => 88 cm = Perimeter of figure
