A=(Length)(width) [Use the formula for the area of a rectangle] \n" ); document.write( "104=(5w)(w) [Plug-in the values that are given] \n" ); document.write( "104=5w^2 \n" ); document.write( "104/5=w^2 \n" ); document.write( "20.8=w^2 \n" ); document.write( "sqrt(20.8=sqrt(w^2) [Find the square root of each side] \n" ); document.write( "4.5607017=w (width) \n" ); document.write( "(5)(4.5607017)=22.8035=l(length) \n" ); document.write( ". \n" ); document.write( "Check by plugging all of the values back into the original equation. \n" ); document.write( "104=(4.5607)(22.8035) \n" ); document.write( "104=103.9999 [Close enough] \n" ); document.write( " \n" ); document.write( " |
