Answer: 3 cm²
Step-by-step explanation:
White triangle tip is in center that means that one side of triangle is even with breadth of flag
a ₁=b=12 cm
Hight of triangle is half of flag length
h₁=a/2=20 cm/2=10 cm
use equatin for area of triangle
A=a₁*h₁/2
A=12*10/2
A=60cm²
Red star takes 5% of white triangle area.
A₂=60 cm²*5%= 60cm²*(5/100)=300cm²/100=3cm²

Answer:
169.5 yd²
Step-by-step explanation:
See attachment.
In situations like this, ALWAYS (!) make as sketch.
Divide the areas by adding dotted lines on sensible places, and write in the missing numbers for the correct distances.
The only possible difficult one is the triangle, which is the half of a rectangle. So you are dealing with a series of areas of rectangles. That is really easy if you understand what you are doing.
Total area =
area 1 + area 2 + area 3 + area 4
10*4 + 4*7 + 3*13 + (0.5 * 7*17)
40 + 28 + 42 + 59.5
Total area = 169.5 yd²
