Perimeter (P) of a square = 4s ; where s is the length of a side
1 yd = 4s
yd = s
Area (A) of a square = s²
= ()²
Now, convert from yard to foot to inch:
()² x (
)² x (
)²
= (3 x 3 x 12 x 12) ÷ (4 x 4)
= 81 in²
; a₁ is the first term, d is the difference between terms, and n is the term
-4, -21, -38, ... ⇒ a₁ = -4, d = -17
= -4 - 17n + 17
= 13 - 17n
= 13 - 1088
= 1075
Answer: 1075
