The population density of peru one year was approximately 23 people per square kilometer. brazil has a land area of approximately 8.5 million square kilometers.

if brazil had the same population density as peru that year, approximately how many people were living in brazil

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.
