Answer:126m2
Explanation:
Since they are both rectangles, use the area of a rectangle equation to find it which is length times width. What I would do first is find the area of the big rectangle which is 10*15 which is 150. Then I would find the area of the white space which is 6*4 which is 24. Since the white space is not part of the question, subtract 24 from 150 which gets you 126m2. Hope this helps :)
