Answer :

Answer:

69 yards

Step-by-step explanation:

Perimeter = 2(length + width)

300 = 2(81 + width)

150 = 81 + width

width = 69

Step-by-step explanation:

Step 1:  Find the width

[tex]P = 2(L * W)[/tex]

[tex]300 = 2(81 * W)[/tex]

Distribute

[tex]300 = 2(81 * W)[/tex]

[tex]300 = (2 * 81) + 2W[/tex]

Subtract 162 from both sides

[tex]300 = (2 * 81) + 2W[/tex]

[tex]300- 162 = 162 - 162 + 2W[/tex]

[tex]138 = 2W[/tex]

Divide both sides by 2

[tex]138 / 2 = 2W / 2[/tex]

[tex]69 = W[/tex]

Answer:  The width is 69 yards
