Algebra.Com's Answer #104693 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! The perimeter of a rectangle is 178 inches. The length exceeds the width by 15 inches. Find the width and the length. \n" ); document.write( ": \n" ); document.write( "Let x = the width \n" ); document.write( ": \n" ); document.write( "It says,\"The length exceeds the width by 15 inches.\" so we can say: \n" ); document.write( "(x+15) = the length \n" ); document.write( ": \n" ); document.write( "we know,\"The perimeter of a rectangle is 178 inches.\" \n" ); document.write( "2L + 2W = 178 \n" ); document.write( ": \n" ); document.write( "Substitute (x+15) for L and x for w, and find x (the width) \n" ); document.write( "2(x+15) + 2x = 178 \n" ); document.write( ": \n" ); document.write( "2x + 30 + 2x = 178 \n" ); document.write( ": \n" ); document.write( "2x + 2x = 178 - 30 \n" ); document.write( ": \n" ); document.write( "4x = 148 \n" ); document.write( "x = \n" ); document.write( "x = 37 inches is the width \n" ); document.write( "then \n" ); document.write( "37 + 15 = 52 inches the length \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Check solution by finding the perimeter with these values: \n" ); document.write( "2(52) + 2(37) = 178 \n" ); document.write( ": \n" ); document.write( ": \n" ); document.write( "Do you understand it now? \r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
