Calculate the Trapezoid's Perimeter: Using Given Base and Side Lengths

Calculate the perimeter of the trapezoid below:

To solve this problem, we'll use the perimeter formula for a trapezoid, which is straightforward since all side lengths are provided:

• Step 1: Identify the side lengths:
  Top base ($a$): $12.28$ units
  Bottom base ($b$): $17.5$ units
  Left non-parallel side ($c$): $5.1$ units
  Right non-parallel side ($d$): $6$ units
• Step 2: Apply the formula for the perimeter, which states:
  $P = a + b + c + d$
• Step 3: Substitute the known values into the formula:
  $P = 12.28 + 17.5 + 5.1 + 6$
• Step 4: Perform the addition:

Calculating the sum:

$12.28 + 17.5 = 29.78$

$29.78 + 5.1 = 34.88$

$34.88 + 6 = 40.88$

Hence, the perimeter of the trapezoid is $40.88$ units.
