Answer:

A(s) = 42.25 km ²

Step-by-step explanation:

P(r) = 2l + 2w = 2×8km + 2×5km = 16km + 10km = 26 km

P(r) = P(s)

P(s) = 26 km = 4l => l = 26km/4 = 6.5 km

A(s) = l² = (6.5km)² = 42.25 km ²

Answer:

3a+6

Step-by-step explanation:

3a+6 = 24a+48 divided by 8 (there are 8 sides in an octagon)

covert 3a+6 inches into feet

0.25a +0,5

0.25(7)+0.5

= 2.25

verify your answer

2.25 x 8 = 18
