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

Answer 1

Answer: 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 2

Answer:

Answer: B - 1.69%

I took the test, trust me.

Hector has a rectangular garden that measures 13 m wide by 15 m long. He wants to increase the area to 255 m2 by increasing the width and length by the same amount. What will be the length (longer dimension) of the new garden?

Answers

let x be the length loner
(15+x)*(13+x)=255
x^2+28x+195=255
x^2+28x-60=0
( x-2)(x+30)=0
x=2 or x=-30 (rejected)
Therefore the length longer is 2 m
