Question

find perimeter by measuring lengths
supported practice
enter the perimeter.
diagram of a brown dotted shape with two rulers (horizontal and vertical) measuring it, and an input box labeled cm

Explanation:

Step1: Determine the side length

From the ruler, the length of one side of the square (since it's a square - like figure) is 8 cm (measured from 0 to 8 on the horizontal ruler, and the vertical side also measures 8 cm as seen from the vertical ruler).

Step2: Calculate the perimeter of a square

The formula for the perimeter of a square is \( P = 4\times s \), where \( s \) is the side length. Substituting \( s = 8 \) cm, we get \( P=4\times8 = 32 \) cm.

Answer:

32
