Algebra.Com's Answer #121472 by MRperkins(300)![]() ![]() You can put this solution on YOUR website! We know the formula for a rectangle is P=L+L+W+W or P=2L+2W \n" ); document.write( "We are given L=26cm and P>80 \n" ); document.write( "In order to find out when P>80 we need to know when P=80. \n" ); document.write( "So plug this into the formula and you get: \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Now subtract 52 from each side: \n" ); document.write( " \n" ); document.write( "Divide both sides by 2 and you get \n" ); document.write( "\n" ); document.write( "We have found the width that will make the perimeter exactly 80 cm. However, we want a perimeter greater than 80 cm. So any width greater than 14 cm will work. \n" ); document.write( " |
