How do you 'find the ratio of its length to its perimeter?

To find the ratio of the length of a shape to its perimeter, you would divide the length by the perimeter. For example, if the length of a rectangle is 4 units and its perimeter is 12 units, the ratio would be 4/12 or 1/3. This ratio represents the proportion of the length to the total distance around the shape.

What is the perimeter 7cm 8cm 12cm?

Oh, what a delightful question! To find the perimeter of a shape, you simply add up all the sides. So for a shape with sides measuring 7cm, 8cm, and 12cm, you would add them together to find the total perimeter. In this case, the perimeter would be 7cm + 8cm + 12cm = 27cm. Just imagine all those sides coming together like old friends for a lovely little stroll around the shape!
