Respuesta :

We can find the area of a rectangle by multiplying its length and width.

11 * 5 = 55

So, 55 is the area of the rectangle.
Your answer would be 55. 
All you really have to do is multiply them together. 

l x w = a (the area)
11 x 5 = 55 

I hoped I helped and if you need more you could always ask me :)
