Answer is 4:7</h3>
Explanation:
There are 20 yellow triangles and 15+20 = 35 triangles total.
The ratio of yellow to total is 20:35. The order is important.
We divide both parts by the GCF 5 to get the reduced ratio 4:7
450
10*12= 120 the bottom of the box
10*7.5= 75 one side
75*2= 150 two sides
12*7.5= 90 another side
90*2= 180 two other sides
120+150+180 = 450
Hope this helped :)
