Question 152044
{{{AreaOfRectangle = Length*Width}}}
The area of the light swtich is the area of the plate minus the area of the hole
{{{Area = AreaPlate - AreaHole}}}
{{{Area = (7*5.5) - (1.2* 0.3)}}}
{{{Area = 38.5 - 0.36}}}
{{{Area = 38.14}}} square inches

At 4.27 per square inch, the toal cost is {{{Cost = 4.27 * 38.14}}}
{{{Cost = 162.86}}} 

That's one expensive light switch.
