Answer:
288m^2
Step-by-step explanation:
ratio is 4000/3, though the thousand does not matter because we can just exchange units
18*4/3=24
24 meters
9*4/3=12
12 meters
24*12=288
Answer:
Q = 52.5
Step-by-step explanation:
given P is directly proportional to Q then the equation relating them is
P = kQ ← k is the constant of proportion
to find k use the condition Q = 30 when P = 40 , then
40 = 30k ( divide both sides by 30 )
=
= k
P =
Q ← equation of proportion
when P = 70 , then
70 =
Q ( multiply both sides by 3 to clear the fraction )
210 = 4Q ( divide both sides by 4 )
52.5 = Q
