Answer:
The length of each side of square is 5ft.
Step-by-step explanation:
Given:
A composite figure is formed by combining a square and a triangle. Its total area is 32.5ft squared.
The area of the triangle is 7.5ft squared.
Now, to find the length of each side of square.
Now, we need to get the area of the square first:
Area of combined figure - area of triangle = area of square.
32.5 ft squared - 7.5 ft squared = 25 ft squared.
So, area of square = 25 ft squared.
Now, by putting the formula for getting the length of each side:
Let the side = a.
Area of square = 25 ft squared
Area of square = a²
Using square root both sides we get:
So, the side = 5 ft.
Therefore, the length of each side of square is 5ft.
The perimeter of the figure in simplified form is expressed as: P = 2p + 2q + 2r + 4s
<h3>How to find the Perimeter of a Figure</h3>
To find the perimeter of any figure, add all the side lengths of the figure together.
Thus, the given side lengths of the figure are:
p, p, q, q, r, r, s, s, s, and s.
To find the perimeter add them together.
Perimeter of the figure = p + p + q + q + r + r + s + s + s + s
Perimeter = 2p + 2q + 2r + 4s
Therefore, the perimeter of the figure in simplified form is expressed as: P = 2p + 2q + 2r + 4s

<h3>
Answer: approximately 5.1724%</h3>
Work Shown:
2 hrs, 45 min = 120 min + 45 min = 165 min
2 hrs, 54 min = 120 min + 54 min = 174 min
A = estimated value = 165
B = true value = 174
C = percent error
C = 100*( |A - B| )/B
C = 100*( |165-174| )/174
C = 100*( | -9 | )/174
C = 100*9/174
C = 900/174
C = 5.1724% which is approximate
