Question

what is the perimeter of this parallelogram?
12.9 ft
1.1 ft
______ feet

Explanation:

Step1: Recall the perimeter formula for a parallelogram

The perimeter \( P \) of a parallelogram is given by the formula \( P = 2(a + b) \), where \( a \) and \( b \) are the lengths of two adjacent sides.

Step2: Identify the side lengths

From the diagram, we can see that the lengths of the adjacent sides are \( a = 12.9 \) ft and \( b = 1.1 \) ft.

Step3: Substitute the values into the formula

First, calculate the sum of the two adjacent sides: \( a + b = 12.9 + 1.1 = 14 \) ft.
Then, multiply this sum by 2 to find the perimeter: \( P = 2\times14 = 28 \) ft.

Answer:

28
