Answer:
The actual park has 0.7776 square meters
Step-by-step explanation:
To solve this we first have to find the value of the scale
We know that the width of the model is 8cm and that of the true park is 72cm², so if we divide 72 by 8 we will obtain the value of the scale
72 / 8 = 9
To find out how much the park area has, the park first we have to multiply 96cm² by the scale
As the scale of 9 is made for width and length, when we calculate the area it will be multiplied 2 times by 9, so to calculate the real area we have to multiply it 2 times
96cm² * 9 * 9 = 7776cm²
if we want the result in square meters we simply have to divide the result by 100²
7776cm²/100² = 7776cm² / 10,000
0.7776m²
The actual park has 0.7776 square meters
