Answer:
Step-by-step explanation:
By taking k as constant:
P = k/L (where P is pressure, and L is length)
5 = k/2
k = 10
Therefore:
P = 10 / L
P = 10/ 8
P = 1.25 Pounds.
Considering the figures, the area that will be painted is of 38.9 square feet.
<h3>What is the area of a rectangle?</h3>

<h3>What is the area of a semi-circle?</h3>
The area of a semi-circle of radius r is given by:

In this problem:
- The rectangle with l = 6 ft and w = 8 ft will be painted, along with the triangle of dimensions b = 8 ft and h = 4 ft.
- The semi-circle with r = 4 ft will not be painted.
Hence, the area that will be painted, in square feet, is given by:
