<span>The
causes of environmental problems in Sub-Saharan Africa are deforestation,
development, and increased population. As the country is aiming for development,
its environmental status is impaired. Increasing population resulted to
migration to higher urban or rural areas, and continuous land cultivation which

Answer:
2.5 km = 250000 cm
500 ft = 15240 cm
Explanation:
part a
given data
length = 2.5 km
to find out
Convert into cm
solution
we know that 1 m = 100 cm ...............1
and also we know 1 km = 1000 m .................2
sop as that we can say from equation 1 and 2
1 km = 100000 cm
so for 2.5 km = 2.5 × 100000 cm
2.5 km = 250000 cm
and
part b
given data
length = 500 ft
to find out
Convert ft into cm
solution
we know here that
1 ft = 12 inches ..................1
and also we know 1 inch = 2.54 cm ...................2
so we can say
500 ft = 12 × 500 inches
500 ft = 6000 inches
and 500 ft = 6000 × 2.54 cm
500 ft = 15240 cm
