p +d = 74 coins
rewrite as p =74-d
0.01p + 0.10d = 4.61
0.01(74-d) +0.10d = 4.61
0.74 - 0.01d +0.10d =4.61
0.74 +0.09d =4.61
0.09d = 3.87
d = 3.87/.09 = 43
p = 74-43 = 31

Answer:
Area of Triangle = 1/2 bh
A = 1/2 (16 cm x 10 cm)
A = 160 cm2/2
A = 80 square cm
Area of Circle =
d2/4
A = 3.14 x (16 cm)2 / 4
A = 3.14 x 256 cm2 / 4
A = 803.84 cm2 / 4
A = 200.96 cm2
Area of Half Circle = 200.96 cm2 / 2
A = 100.48
Composite Figure = Area of Triangle + Area of half Circle
Area of Composite Figure = 80 cm2 + 100.48 cm2
Area of Composite Figure = 180.48 cm2
