Quiz 3.2.1 - Properties of Parallelograms
The perimeter of the parallelogram below is 32.2. What equation would you set up to solve for $x$ ? Wh is the value of $x$ ? Select two answer and round to the nearest tenth if necessary.
[mark all correct answers]
a. $3 x-8+16=32.2$
b. $3 x-8+16+3 x-8+16=32.2$
c. $3 x-8=16+32.2$
d. 8
e. 5.3
f. 27
Solution
Solution Steps
Step 1: Understand the Problem
The problem involves finding the value of \( x \) in a parallelogram where the perimeter is given as 32.2. The sides of the parallelogram are labeled with expressions involving \( x \).
Step 2: Identify the Sides of the Parallelogram
In the parallelogram \( URST \):
\( UR \) and \( TS \) are each 16 units.
\( UT \) and \( RS \) are each \( 3x - 8 \) units.
Step 3: Set Up the Perimeter Equation
The perimeter of a parallelogram is the sum of all its sides. Therefore, the equation for the perimeter is:
\[ 2(16) + 2(3x - 8) = 32.2 \]
Step 4: Simplify the Equation
Simplify the equation to solve for \( x \):
\[ 32 + 6x - 16 = 32.2 \]
\[ 6x + 16 = 32.2 \]
\[ 6x = 32.2 - 16 \]
\[ 6x = 16.2 \]
Step 5: Solve for \( x \)
Divide both sides by 6 to find \( x \):
\[ x = \frac{16.2}{6} \]
\[ x = 2.7 \]
Final Answer
The correct equation to set up is:
\[ 3x - 8 + 16 + 3x - 8 + 16 = 32.2 \]
The value of \( x \) is:
\[ x = 2.7 \]
