Algebra.Com's Answer #143576 by kara!(17)![]() ![]() ![]() You can put this solution on YOUR website! \n" ); document.write( " A= 104sq. feet \n" ); document.write( " Formula for the area of the rectangular room is: A=L*W( lenght times width) \n" ); document.write( " because Lenght is 5 feet longer, it's going to be :L= W+5 \n" ); document.write( "Let's put it in a formula \n" ); document.write( " (W+5)*W= 104 \n" ); document.write( " W^2+5W-104=0 \n" ); document.write( " after we solve this equation, we are going to find two answers, one is W=8 \n" ); document.write( "the other W=-13( this can't be solution, because it's negative, and width of the room can't be negative number) \n" ); document.write( " To find a Lenght, we will add 5 feet to the widht: L=8+5=13. \n" ); document.write( "So, the dimensions of the room are, 13ft and 8ft. \n" ); document.write( " \n" ); document.write( " |
