I hope this helps you
f(8)=2.8+5=21
g(8)=3.8+6=30
f-g(8)=21-30= -9
P = 2(L + W)
P = 68.4
L = 4W + 9.7
68.4 = 2(4W + 9.7 + W)
68.4 = 2(5W + 9.7)
68.4 = 10W + 19.4
68.4 - 19.4 = 10W
49 = 10W
49/10 = W
4.9 = W <==== the width is 4.9 cm
L = 4W + 9.7
L = 4(4.9) + 9.7
L = 19.6 + 9.7
L = 29.3 <=== the length is 29.3 cm

We have three pairs of rectangles:
16ft × 6ft = 96ft²
2ft × 6ft = 12ft²
2ft × 16ft = 32ft²
S.A. = 2 × (96 + 12 + 32) = 2 × 140 = 280ft².
<h3>Answer: C.) 280ft²</h3>
