Answer: 36 feet of wood
Step-by-step explanation:
P=perimeter. P=total length of wood
s= side length. A=area
A=s^2
81=s^2
s^2=9^2
s=9
P=4s
P=4(9)
P=36 feet of wood
Answer:
P = 36 ft
Step-by-step explanation:
The given length is,
→ a = ?
Formula we use,
→ A = a²
Now the length of one side is,
→ A = a²
→ a² = 81
→ a = √81
→ [ a = 9 ]
The total length of wood needed is,
→ P = 4a
→ P = 4 × 9
→ [ P = 36 ]
Hence, the total length is 36 ft.
