Algebra.Com's Answer #192472 by Stitch(470)![]() ![]() ![]() You can put this solution on YOUR website! The area of a rectangle is found by multiplying the length by the width. In your example, only the width was given so we need to find the length.\r \n" ); document.write( "\n" ); document.write( "The Pythagorean theorem states that in any right triagle, \n" ); document.write( "Where C is the hypotenuse (or the diagonal)\r \n" ); document.write( "\n" ); document.write( "A and B represent the sides of the triangle but it does not matter which one so We will set A = 6 (the given width) \n" ); document.write( "and C = 10 (hypotenuse)\r \n" ); document.write( "\n" ); document.write( "The equation: \n" ); document.write( "Subtract 36 from both sides \n" ); document.write( " \n" ); document.write( "Take the square root of both sides \n" ); document.write( " \n" ); document.write( "The length of the retangle is 8\r \n" ); document.write( "\n" ); document.write( "Now we can find the area of the rectangle: \n" ); document.write( "A = L * W \n" ); document.write( "Area = 8 * 6 \n" ); document.write( "Area = 48 square units \n" ); document.write( " \n" ); document.write( " |
