Algebra.Com's Answer #14085 by queenofit(120)![]() ![]() ![]() You can put this solution on YOUR website! Ok first I will assume that when you said side A is tice side B, you meant twice, OK?. You need to know several things to find this answer. First, of course, you need the formula for the perimeter which is side +side +side. You have 3 sides. We will call them side A B and C. You know they equal 98 meters. now, to find the sides. First look at the question. The only variable you would have that does not have a number involved is your B side. So we will set up our equation as if we are solving for B, ok. this is what you know from the equation \n" ); document.write( "B=B \n" ); document.write( "A= 2B (side A is twice side B) \n" ); document.write( "C=2B-2 (side C is 2 meters shorter than side A, which is 2B)\r \n" ); document.write( "\n" ); document.write( "To get perimeter you add these three together and set them equal to 98\r \n" ); document.write( "\n" ); document.write( "2B + B + 2B - 2 = 98 (do you see how I set A + B + C = 98) \n" ); document.write( "5B-2=98 (combine like terms) \n" ); document.write( "5B=100 (solve using algebra) \n" ); document.write( "B=20 (side B = 20 meters) \n" ); document.write( "A= 2*20=40 (side A= 40 meters) \n" ); document.write( "C= 2*20-2=38 (side C = 38 meters)\r \n" ); document.write( "\n" ); document.write( "check by adding A + B + C = 98 \n" ); document.write( "20+40+38=98\r \n" ); document.write( "\n" ); document.write( "I hope this helps, if you need further assistance, please let me know. \n" ); document.write( "A. \n" ); document.write( " |
