Unfortunately, there is no diagram attached to this question for me to provide a specific answer. However, I can provide a general method for solving this type of problem.

Let's denote the area of Square A as "a" and the area of Rectangle B as "b". Before the overlapping, the total area of Square A and Rectangle B is given by:

• a + b

According to the problem, the ratio of the unshaded area to the total area before overlapping is 17:23. This means that the unshaded area is (17/40) times the total area before overlapping:

• unshaded area = (17/40) x (a + b)

To find the shaded area, we can subtract the unshaded area from the total area before overlapping:

• shaded area = (a + b) - (17/40) x (a + b)

Simplifying this expression, we get:

• shaded area = (23/40) x (a + b)

Finally, the ratio of the shaded area to the total area before overlapping is:

• shaded area : (a + b) = (23/40) : 1

or simply:

• shaded area : total area = 23 : 40

So, the ratio of the shaded area to the total area of Square A and Rectangle B before the overlapping is 23:40.

Penjelasan dengan langkah-langkah:

Persegi panjang adalah bangun datar yang tersusun atas dua pasang sisi yang saling tegak lurus namun setiap pasang sisi berbeda panjang dengan pasangan sisi lainnya.

Persegi panjang sering kali dianggap sebagai bujur sangkar yang memanjang karena beberapa sifat persegi panjang yang menyerupai bujur sangkar, antara lain :

• Memiliki 4 sisi, namun 2 antaranya memanjang,
• Memiliki 4 titik sudut,
• Memiliki 2 diagonal.
