First triangle=bxh/2
=3x4/2
=6in squared
rectangle=l x w
=3 x 10
=30in squared
trapezoid=3+5x2/2
=8in squared
6 + 30 + 8

APY = (1 + r/n)^n - 1
r = interest rate
n= number of times compounded
APY = (1 +0.065/365)^365 - 1
= 6.715%
I think the answer is a = 4.5
81 ÷ 6 ÷ 3 = 4.5
I hope this helps, have a wonderful day!
