2*(L+W) where L is the length and W is the width of the poster
A yardstick or ruler!
To find the perimeter of a poster, you need to know its length and width. The perimeter is calculated by the formula: P = 2(length + width). For example, if a poster measures 24 inches by 36 inches, the perimeter would be 2(24 + 36) = 120 inches.
2/1
Let the width be x/2 and the length be x: (x/2)*x = 128 Multiply both sides by 2 and remove the brackets: x2 = 256 Square root both sides: x = 16 Therefore: length = 16 feet and width = 8 feet Check: 16*8 = 128 square feet
L = 2W 2W x W = 128 2W squared = 128 w squared = 64 W = 8 Width 8 ft, length 16 ft 8 x 16 = 128 QED
24 times 24. duhhh
To measure the perimeter of a poster board, first measure the length and width using a ruler or measuring tape. The perimeter can be calculated using the formula: Perimeter = 2 × (Length + Width). Simply add the length and width together, multiply the sum by 2, and you'll have the total perimeter measurement.
Let the width be x/2 and the length be x: (x/2)*x = 128 Multiply both sides by 2 and remove the brackets: x2 = 256 Square root both sides: x = 16 Therefore: length = 16 feet and width = 8 feet Check: 16*8 = 128 square feet
