helpfulThe length of the rectangle = (3½ + 8½) = 12 in
The breadth of the rectangle = 8 in
So, the area of the rectangle can be calculated as :
Area = Length × Breadth = 12 × 8 = 96 in²
Now, as we can se the two white regions in the flag form identical triangle with base = 8½ in and height = 8 in.
Thus, area of each triangle can be calculated as :
Area = ½ × base × height = ½ × 8½ × 8 = 34 in²
So, area of both triangles = 2 × 34 = 68 in²
Thus, the area of black stripe = Area of rectangle - Area of both triangles
= (96 - 68)
= 28 in²
