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

the answer to the expression is 83

there is no grid
