Please help, i have 5 minutes left!! no joke please help :(

The answer is the scale factor greater than 1.

Step-by-step explanation:  We are asked that by what we must multiply the original number to make it bigger.

Suppose, we have a regular polygon, i.e., all sides have same measurement. Then, we must multiply any side of the original figure by the quantity called scale factor and the result will be one of the sides of the bigger polygon, which is also regular.

Also, here the scale factor must be greater than 1 to get a bigger figure. If we take scale factor less than 1, then the new figure will be smaller than the original one.

For example, see the attached figure, equilateral triangle ABC with each side 5 cm is enlarged to another equilateral triangle DEF with each side 7.5 cm. Also, here the scale factor is 1.5, which is greater than 1.

Thus, the answer is the scale factor greater than 1.
