Red + green = 24; (1)
red + blue = 10; (2)
blue + green = 20; (3)
(1) - (2):
green - blue = 14; (4)
(3) + (4):
2 * green = 34;
green = 17;
Simple substitution gives:
blue = 3;
red = 7;

Answer:
784
Step-by-step explanation:
A = 1/2ap A = area , a = apothem , p = perimeter
a = 1/2s a = apothem length , s = side length
14 = 1/2s , 14(2) = 1/2s(2) , 28 = s
p = 4(s) , p = 4(28) , p = 112
A = 1/2ap , A = 1/2(14)(112) , A = 784
or
A = s^2 , A = 28^2 , A = 784
