A builder has bought a plot of land on which he will build a house. The plot is a rectangle with an area of 50,000 square feet. The following coordinates have been marked on a coordinate plane by the builder; (60, 60), (60, 110), and (160, 110). What is the coordinate of the fourth vertex of the rectangle plot?

Answers

The answer (160, 60) because my sister taught me if it is a square or a rectangle like the coordinates that you gave me, take out the numbers that are the same and in the same area as the number is.

Ross needs to buy a countertop for a laundry room. He calculated the area to be 12 square feet. The actual area is 11.8 square feet. What is Ross's percentage error?

Answers

The formula for percentage error is:

\sf{Percentage~ error= (|Approximate ~-~ Actual|)/(|Actual|)}

Ross got the approximate area as 12, while the actual area was 11.8. So, let's plug it in to the formula.

\sf{Percentage~ error= (|Approximate ~-~ Actual|)/(|Actual|)= (|12-11.8|)/(|11.8|)= (|0.2|)/(|11.8|)= (0.2)/(11.8) \approx 0.0169 }

Multiply 0.0169 by 100 to make it into a percent.

0.0169 * 100 = 1.69%

Ross's percentage error is 1.69%.

Answer: B - 1.69%
