document.write( "Question 828950: Suppose that the perimeter of a rectangle is 66 and the lenght is twice the width. what is the dimensions of the rectangle and what is the area \n" ); document.write( "
Algebra.Com's Answer #499832 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! A perimeter is a fence around something. To fence a rectangle, you need 2 pieces of the length and 2 pieces of the width. \n" ); document.write( "2L + 2W = P \n" ); document.write( "The question gives you the following: \n" ); document.write( "P = 66 \n" ); document.write( "L = 2W \n" ); document.write( "Plug in the numbers: \n" ); document.write( "2(2W) + 2W = 66 \n" ); document.write( "Multiply: \n" ); document.write( "4W + 2W = 66 \n" ); document.write( "Add the Ws: \n" ); document.write( "6W = 66 \n" ); document.write( "Divide by 6 \n" ); document.write( "W = 11 \n" ); document.write( ". \n" ); document.write( "Now that you have the width, you can find the length. \"the length is twice the width\" L = 2*11, or 22. \n" ); document.write( ". \n" ); document.write( "Let's prove this correct. \n" ); document.write( "2L + 2W = 66 \n" ); document.write( "2(22) + 2(11) = 66 \n" ); document.write( "44 + 22 does indeed equal 66. \n" ); document.write( " |
