Let the dimensions of a square be x by x. So if we increase the sides by 2. Then we have an x+2 by x+2. So the area of the square is $\"%28x%2B2%29%5E2\"$ . Set that equal to 49.\r
\n" ); document.write( "\n" ); document.write( " $\"%28x%2B2%29%5E2+=+49\"$
\n" ); document.write( "Take the square root of both sides and get that the square root of 49 is 7 or -7. But remember we are talking about length, so -7 is not possible.\r
\n" ); document.write( "\n" ); document.write( " $\"x%2B2+=+7\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"highlight%28x+=+5%29\"$ \n" ); document.write( "
