.

Answer 1

Answer:

Step-by-step explanation:

area of the roads is as follows

area of first road=

len=45

bre=5

area of first road =l×b

=45×5

=225cm2

area of second road=

len=70

bre=5

area=l×b

70×5

350cm2

total area of roads=area of 1st road +area of second road -s×s

225+350-5x5

550cm2
