Worked Solution

Step 1: A rectangle has two lengths and two widths. Length = 8 cm, width = 5 cm. Step 2: Perimeter = length + width + length + width = 8 + 5 + 8 + 5. Step 3: 8 + 5 = 13, and 13 + 13 = 26 cm. (Or use the formula 2 x (8 + 5) = 2 x 13 = 26 cm.) Final answer: 26 cm. Answer: 26 cm

Correct answer: 26 cm
