To find the perimeter of a trapezoid, you add the lengths of all four sides together.
Given the side lengths of the trapezoid:
- Side 1: 8 ft
- Side 2: 14 ft
- Side 3: 16 ft
- Side 4: 12 ft
Now, sum these lengths:
\[ \text{Perimeter} = 8 , \text{ft} + 14 , \text{ft} + 16 , \text{ft} + 12 , \text{ft} \]
Calculating this gives:
\[ \text{Perimeter} = 8 + 14 + 16 + 12 = 50 , \text{ft} \]
Therefore, the perimeter of the trapezoid is 50 ft.
It seems that you also provided additional numbers (98 ft, 78 ft, 36 ft). If you meant to include those as lengths for a different trapezoid or shape, please clarify, and I'll assist you accordingly!
