# What is the perimeter of a rectangle that has a diagonal of 14 units and a side of length 6 units?

The perimeter would be $12 + 8 \sqrt{10}$ units= 37.30 units(rounded to one decimal point.
With a diagonal of 14 units and a side length of 6 units, the other sid length would be $\sqrt{{14}^{2} - {6}^{2}} = \sqrt{160} = 4 \sqrt{10}$units.
The perimeter would be $12 + 8 \sqrt{10}$ units= 37.30 units(rounded to one decimal point.
