The correct answer is option 'D'. The shaded triangles are the difference between the area of the large square and the area of the small square. The area of the large square is 10cm x 10cm = 100cm^2 and the area of the small square is 8cm x 8cm = 64 cm^2. Therefore, the area of the shaded triangle is 100cm^2 - 64 cm^2 = 36 cm^2. Since there are 8 identical shaded triangles, the total area of all the shaded triangles is 8 x 36 cm^2 = 288 cm^2.

The figure given below shows 8 identical triangles in 2 squares each o...
To find the area of the shaded triangles, we need to calculate the area of one triangle and then multiply it by 8 since there are 8 identical triangles.
1. Calculating the area of one triangle:
The triangles are identical, so they all have the same dimensions. Let's call the base of the triangle b and the height h. We can see that the base of the triangle is equal to the side length of one of the squares, which is 10 cm. The height of the triangle is equal to the side length of the other square, which is also 10 cm.
The formula for the area of a triangle is A = 1/2 * base * height. Plugging in the values, we get:
A = 1/2 * 10 cm * 10 cm
A = 1/2 * 100 cm^2
A = 50 cm^2
2. Multiplying the area of one triangle by 8:
Since there are 8 identical triangles, we need to multiply the area of one triangle by 8 to get the total area of all the shaded triangles.
Total area = 50 cm^2 * 8
Total area = 400 cm^2
Therefore, the correct answer is option 'D' - 100 cm^2.
