The park zone of the city is 3400 hectares, then it was increased by 1/8 what is the area of the park zone.

We will solve this problem through the conditional variable “Y”, through which we will designate the new area of the park zone.
At the second stage, using the information of the example, we get the following expression: Y = 3400 x (1 + 1/8).
The result of the calculation made has the following result Y = 3400 x (1 x 8 + 1) / 8 = 3400 x (8 + 1) / 8 = 3400 x 9/8 = 425 x 9 = 3825 ha.
Answer: 3825 hectares.
