The area of a square mirror is 256 in². a rectangular mirror has a width the same as the square mirrors width. its length is two inches longer than its width. what is the area of the rectangular mirror?

Area (square mirror)=side²
Therefore:
side²=256 in²
side=√(256 in²)=16 in

Rectangular mirror:
width= square mirror width=side=16 in
length=(width + 2 in)=16 in + 2 in=18 in.

Area(rectangular mirror)=length x width.
Area (rectangular mirror)=(18 in)(16 in)=288 in².

the area of a rectangular mirror is 288 in².
