Answer 1

Hello there. To solve this question, we need to remember some properties on metric conversion.

As you can see, we have an area given in acres and we want to find its value on the square feet metric.

Using the dava given on the chart (1 acre = 43.560 square feet (ft²)), we'll have the following configuration:

1/435.6 = 43560/x

In which x is the value in square feet we want to find.

Cross multiplying the values, we'll get:

Multiplying these values, we get:

x = 18.974.736 ft²
