Given the flag of djibouti with length 20 cm and breadth 12 cm. The red star take up 5% of the area of the white triangle. The w
hite triangle's tip is in the center of the flag. Find the area of the red star?
1 answer:
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
