Question

four sides of a octagon each measure 12 cm. the perimeter of the octagon is 70 cm. what is the length of each remaining side, if each remaining side has the same length?
enter your answer in the box.
□ cm

Explanation:

Step1: Calculate total length of 4 sides

$\text{Total length} = 4 \times 12 = 48$ cm

Step2: Find total length of remaining sides

$\text{Remaining total} = 70 - 48 = 22$ cm

Step3: Calculate length of each remaining side

An octagon has 8 sides, so remaining sides = $8-4=4$.
$\text{Length per side} = \frac{22}{4} = 5.5$ cm

Answer:

5.5 cm
