Write an equation that relates the number of trapezoids in t

Write an equation that relates the number of trapezoids in the figure (n), to the perimeter of the figure (P). The equation for the perimeter is P = 14n + 5. The equation for the perimeter is P = 5n + 14. The equation for the perimeter is P = 5n +8. The equation for the perimeter is P = 14n + 10.

Solution

1-- trapezoid Perimeter 1 = 8+5+5+6 = 24

2---- trapezoids Perimeter 2 = 38

3 ---- trapezoids ; Perimeter = 52

common diffrenec d= 14 ; a1 = 24

nth term : an = 24 +(n-1)14

= 14n +10

So, Last option P = 14n +10
