A pattern has 12 red squares to every 84 blue circles
The ratio is shown below;
Step-by-step explanation:
the total area of circles =
(2 × π × 1²) + (3 × π × 0.5²)
= (2π) + ( 3× 0.25×π)
= 2π + 0.75π
= 2.75π
assume π=3.14
so, the total area =
2.75 × 3.14 = 8.635
A = c
b = 180 - a
d = 90
a = 180 - (90 +22.6) = 67.4
x = 5 as the ratio of lengths of the small triangle to big triangle is 1:2
therefore if the big triangle has a length 10, then the small one must be 5
