Let's call the short side "s"
short side = "s"
middle side = 3s
longest side = 2*3*s
perimeter = 45 cm
perimeter = s + 3s + 6s = 45
short side = 4.5
middle = 13.5
long side = 27
4.5 + 13.5 + 27 = 45

Answer:
area of arrow=610cm²
Step-by-step
First find the area of the square then the are of the triangle then add together to get the area of the arrow.
1.
Area=length x width
=20cm x 15cm
=300cm²
2.
Area= 1/2 base x height
=1/2 x 20 x 31
=1 x 10 x 31
=310cm²
(NOTE: TO FIND THE BASE YOU ADD THE 15CM FROM THE SQUARE AND THE 2 EIGHT'S FROM THE BOTTOM OF THE TRIANGLE)
3.
Total area or area of arrow
=300cm²+310cm²
=610cm²
