Algebra.Com's Answer #625032 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! I could give you the answer, but let's explore what happens if we substitute 2l, 2w, and 2h in for l, w, and h in the formula \n" ); document.write( "A = 2lw + 2lh + 2wh \n" ); document.write( "We get \n" ); document.write( "A' = 2(2l)(2w) + 2(2l)(2h) + 2(2w)(2h) \n" ); document.write( "A' = 8lw + 8lh + 8wh \n" ); document.write( "which is exactly FOUR times the original area A. \n" ); document.write( " |
