Answer:
D. 96 inches
Step-by-step explanation:
Perimeter (P) = 2L + 2W , Where L is the length and W is the width.
20 ft = 2L + 2(2 ft)
2L = 20 ft - 4 ft = 16 ft
L = [tex]\frac{16}{2}[/tex] ft = 8 ft
1 ft = 12 inches
8 ft = ?
Cross-multiplying this gives; [tex]\frac{8}{1}[/tex] × 12 = 96 inches
Answer: D) 96 inches.
Step-by-step explanation: To calculate the lenght of James' rectangular yard, we need to isolate L from the given formula:
P=2L+2W
P-2W=2L
[tex]L=\frac{P-2W}{2}[/tex]
Now we replace the given values of P and W in the equation:
[tex]L=\frac{20feet-2*2feet}{2}[/tex]
[tex]L=\frac{20feet-4feet}{2}[/tex]
[tex]L=\frac{16feet}{2}[/tex]
[tex]L=8feet[/tex]
1feet=12inches so:
L=8feet*12inches/1feet
L=96 inches.
