Chris is building a rectangular pen for his dog. the dimensions are 12 units long and 5 units wide. he decided his dog needed more space, so he is going to build the pen with a scale factor of 120%. find the new dimensions of the dog pen. explain if the new pen is an enlargement or a reduction.

The dimensions are 14.4 units and 6 units

Step-by-step explanation:

∵ The scale factor is 120%

∴ The new length = 12 × 120/100 = 14.4 units

∴ The new width = 5 × 120/100 = 6 units

∵ The scale factor = 120% = 120/100 = 1.2

∵ The scale factor is greater than 1

∴ The new pen is an enlargement

Note: If the scale factor less than 1, it will be reduction

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
