Tameka's claim is incorrect, because the actual area of the park is 15000 square meters.
The scale measurement of the area of the park is given as:
Square both sides of the ratio
Multiply both sides of the ratio by 6
Evaluate both factors
The above means that the actual area of the park is 15000 square meters.
Hence, Tameka's claim is incorrect

Answer:
b = 81
Step-by-step explanation:
given a² and b are directly proportional then the equation relating them is
a² = kb ← k is the constant of proportionality
to find k use the condition a = 2 when b = 9 , then
2² = 9k
4 = 9k ( divide both sides by 9 )
= k
a² = b ← equation of proportion
when a = 6 , then
6² = b
36 = b ( multiply both sides by 9 to clear the fraction )
324 = 4b ( divide both sides by 4 )
81 = b
