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 white triangle's tip is in the center of the flag. find the area of the red star?

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

the answer is 1/4
