Problem when measuring distances in square kilometers

[Bryan1qr]

Hello, I used the following code to be able to draw areas in km2:

library(leaflet)
library(tidyr)
library(leaflet.extras)

leaflet() %>% 
  addTiles() %>%
  addProviderTiles(
    providers$OpenStreetMap) %>% 
  addCircleMarkers(
    lng = -71.41, lat = -15.86) %>% 
  addMeasurePathToolbar(
    options = measurePathOptions(
      imperial = FALSE,
      showDistances = TRUE)) %>% 
  addDrawToolbar(
    targetGroup = "draws",
    editOptions = editToolbarOptions(
                   selectedPathOptions = selectedPathOptions()))

However, I see that when calculating areas in this unit of measurement it gives me a value 10 times larger than it should be. I think it's a package error.
