Question

Students measured the area of Mr. Gandelman’s classroom. They noted that it is 74.27 square meters. According to measurements indicated in the architect’s plans, the room’s actual area is 78.5 square meters. What is the % error in the students’ measurement?

Answer 1

Personally I think thatthr answer could be 5.38853503%, you can round it however you need.

Step-by-step explanation:

There's a value of error between the noted square meters and the actual room's area. which is 4.23. Using the formula to get the percentage of error is getting the value (78.5 - 74.27 = 4.23) and dividing it by 78.5. Then just multiply it by 100 to get the percentage.
