Answer:
he has 121 cookies now
Step-by-step explanation:
8 times 14 plus 9
8 times 14 = 112 + 9 = 121
121
8 bags of 14 cookies means he bought 112 cookies. Since he already had 9, you add 9 to 112 and get 121 cookies in total.

Trapezoid Formula:
A=a+b/2*h
plug in the numbers
length = x + 2
width = x
x + x + (x+2) + (x+2) = 36 ft
4x + 4 = 36 ft
4x = 32 ft
x = 32 ÷ 4
x = 8 ft
dimensions = length x width
= (x+2) × x
= (8+2) × 8
= 10 ft × 8 ft
