Question

The square in the middle has an

Answer 1

Answer:

4 square units

Step-by-step explanation:

Given that the square we have in the middle of the diagram has an area of 1 square unit, to find the area of the entire angle, all we need to do is decompose and reaarange the other shapes where necessary to form the square in the middle.

See the attachment below showing how we can break and arrange the other shapes to derive their area.

Thus, the 2 smaller triangles can be reaaranged to form the middle square. Since the middle square = 1 unit², each smaller triangle = ½ unit².

The other two medium triangles can be decomposed into 2 smaller triangles, which will give us the middle square.

Therefore, the area if the entire rectangle is:

Middle square = 1 unit²

Two smaller triangles = 1 middle square = 1 unit²

2 medium triangles = 4 smaller triangles = 2 middle squares = 2 units

Area of the entire rectangle = 1 + 1 + 2 = 4 square units
