Question

The perimeter of a miniature football field is 60 inches. If the width of the field is 11 inches, calculate its length.

Answer 1

• 19 inches

Explanation:

Perimeter : 2(L + W) = 60

• L + W = 30
• L + 11 = 30
• L = 30 - 11
• L = 19 inches

Answer 2

The length is 19 inches

Explanation:

Step 1: Determine the length

Perimeter = 2(L + W)

Step 2: Solve for L

60 /2 = 2(L + 11) / 2

30 - 11 = L + 11 - 11

19 = L

Answer: The length is 19 inches
