Answer:

Area: 312

Perimeter: 75

Step-by-step explanation:

Area is l·w

20·16=320

two corners aren't filled

320-9-9=318

Add all the sides for perimeter

17+3+3+13+20+13+3+3=75

Answer:

281 m squared

Step-by-step explanation:

What we can first do is find the top length so we can do

17+3+3=23

then we can multiply it by the side length to get the whole rectangle

23*13=299

and we know each of the little areas is 9, and there are two so

9+9=18

and we can subtract that from the whole rectangle

299-18=281
