Answer:
B
Step-by-step explanation:
Angles in a triangle add up to 180
Take 45 + 90 then subtract the answer from 180
First of all, you need to get them all in the same format, easiest is decimal.
red = 1.25
yellow= 1.40
green = 1.20
blue = 1.50
so the order is blue, yellow, red, and lastly green
Since the perimeter is 45 each side is 7.5 (45 divided by number of sides).
Now the picture already divided the hexagon into one triangle, and you can make another triangle in the bottom left. You can isolate the middle part into a big rectangle and the right part into two triangles.
Area of rectangle: length * width
Area of triangle: (1/2) * base * height
