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:
area is 84
Step-by-step explanation:
perimeter is 38(p)
length (l) is 7cm
width is?(w)
p=2(l+w)
38=2(7+w)
38=14+2w
2w=38-14
2w=24
w=12
area=l*w
12*7
=84
