Answer:
a_n=125×20^(n-1)
Step-by-step explanation:
a_n=x×y^(n-1)
a_3=50000=x×y^2
a_5=20000000=x×y^4
y^2=20000000/50000=400
y=20;x=125
Triangle:
A = 3 x 9 x 1/2 = 13.5
Large rectangle (center):
A = 9 x 12 = 108
Medium rectangle:
A = 4 x 6 = 24
Small rectangle (bottom):
A = 4 x 2 = 8
Figure:
A = 13.5 + 108 + 24 + 8 = 153.5 square feet
