To find the perimeter of a shape with whole number sides, you need to:
1. Identify the shape: Determine the type of shape you are working with (square, rectangle, triangle, etc.).
2. Measure the sides: Use a ruler or measuring tape to measure the length of each side of the shape.
3. Add up the sides: Add the lengths of all the sides together to find the total perimeter of the shape.
4. Round to the nearest whole number: If necessary, round the total perimeter to the nearest whole number.
Example: Find the perimeter of a square with sides that measure 7 centimeters each.
1. Identify the shape: Square
2. Measure the sides: 7 cm x 4
3. Add up the sides: 7 + 7 + 7 + 7 = 28 cm
4. Round to the nearest whole number (not necessary in this example): 28 cm.
Therefore, the perimeter of the square with sides that are 7 centimeters long is 28 centimeters.
