Perimeter means to add up all of the sides. Since it's a rectangle, you have 2 sides that have length b + 7, and 2 sides with length b. So, the polynomial is $\"%28b%2B7%29%2B%28b%2B7%29%2B%28b%29%2B%28b%29\"$ . Simplified, that's 4 b's plus 2 7's: $\"4b%2B14\"$ .\r
\n" ); document.write( "\n" ); document.write( "Area is length times width, or base times height...basically, one side times the other. So, for you: $\"%28b%29%28b%2B7%29\"$ . Distribute your b and you have $\"b%5E2%2B7b\"$ . \n" ); document.write( "
