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, \"A%5E2+%2B+B%5E2+=+C%5E2\"
\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: \"6%5E2+%2B+B%5E2+=+10%5E2%29%0D%0ASimplify+the+equation%0D%0A%7B%7B%7B36+%2B+B%5E2+=+100\"
\n" ); document.write( "Subtract 36 from both sides
\n" ); document.write( "\"B%5E2+=+64\"
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( "\"highlight%28B+=+8%29\"
\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( "
