Ken is adding a ribbon border to the edge of his kite. Two sides of the kite measure 9cm, while the other two sides measure 17cm inches. How much ribbon does Ken need ?

306

306

To find the total amount of ribbon Ken needs, we need to calculate the perimeter of the kite. The perimeter is the sum of all the sides of the kite.

First, let's add up the lengths of the two sides that measure 9cm: 9cm + 9cm = 18cm.

Next, let's add up the lengths of the two sides that measure 17cm: 17cm + 17cm = 34cm.

Finally, let's add the lengths of the sides together: 18cm + 34cm = 52cm.

So, Ken needs 52 centimeters of ribbon to border the edge of his kite.

how do you get 306? The perimeter of the kite in cm is

9+9+17+17

Not sure how the inches come into play.
