The area of a rectangular window is to 306 square centimeters. If the length exceeds the width by 1 centimeters, what are the dimentions?
\n" ); document.write( "How do I solve this problem? I want to learn step by step.\r
\n" ); document.write( "\n" ); document.write( "let width be x
\n" ); document.write( "length = (x+1)
\n" ); document.write( "Area = 306
\n" ); document.write( "..
\n" ); document.write( "Area of rectangle A = L*W
\n" ); document.write( "A= x(x+1)= 306
\n" ); document.write( "x^2+x=306
\n" ); document.write( "add -306 to both sides
\n" ); document.write( "x^2+x-306 = 0
\n" ); document.write( "find factors of 306 such that their product = 306 and their sum is 1
\n" ); document.write( "x^2+18x-17x-306=0
\n" ); document.write( "x(x+18)-17(x+18)=0
\n" ); document.write( "(x-17)(x+18)=0
\n" ); document.write( "the width can be 17 OR -18. width cannot be -18. so ignore.
\n" ); document.write( "width = 17 cm
\n" ); document.write( "length = x+1 = 17+1=18 cm
\n" ); document.write( "..
\n" ); document.write( "the dimensions are 17 by 18 cm
\n" ); document.write( "...
