Question 112333
First find the area of the older television


{{{A=s^2}}} Start with the area of a square



{{{A=(3)^2=3*3=9}}} Plug in s=3 and square it


So the area of the older television is 9 sq cm



Now find the area of the newer model


{{{A=(3.2)^2=(3.2)*(3.2)=10.24}}} Follow the same procedure



So the area of the TV increased from 9 to 10.24 sq cm. Now simply subtract 9 from 10.24 to get



{{{10.24-9=1.24}}}


So the area of the television increased 1.24 sq cm
