Question

The middle square has an area of 1 square unit. What is the area of the entire rectangle in square units? Explain your reasoning.

Answer 1

4

Explanation:

I think its 4 because first, the 2 top tringles make a square, and 1+1=2. Then the 2 bottom ones make 2 more squares because one big triangle is equal to 1 square unit. So, its four.
