What would the area of an actual pool be the scale from the drawing is 3: 1000

the complete question in the attached figure

we know

the pool in the drawing is 15x7.5    and the scale is 3/1000

then

if the size in the drawing  is 3----------------------> the actual is 1000

15------------------------------------< X

x=15*1000/3=5000 cms----- > 50 m

and

if the size in the drawing  is 3----------------------> the actual is 1000

7.5------------------------------------< X

x=7.5*1000/3=2500 cm--------> 25 m

the actual area of the pool is 50*25=1250 m²

the answer is 1250 m²

Population next year = 1.075p

Step-by-step explanation:

The current population can be represented by 1 p the increase in the population number by next year is 7.5% p or 7.5/100 p that equals to 0.075p. The expression that represents the expected population by next year is:

Population next year = This year population + expected growth

Population next year = 1p + 0.075p = 1.075p
