Question

The width of a rectangle measures (9s+6)(9s+6) centimeters, and its length measures (s+1)(s+1) centimeters. which expression represents the perimeter, in centimeters, of the rectangle?

Answer 1

P= ( 18s + 12 ) + ( 2s + 2 ) or just P = 20s + 14

Explanation:

9s + 6 is said twice just add both together and it is. 18s + 12.

Same with s + 1 so it would be 2s + 2.

You can add it all together and its 20s + 14.

P = Perimeter.
