The technology lab will be a rectangular room with an area of 600 square feet. In Cody’s drawing of the lab, the scale is 1 inch = 2 feet. In Paola’s drawing, the scale is 1 inch = 5 feet, and one side of the lab measures 5 inches. What are the dimensions of the lab in Cody’s drawing? Explain.

The dimensions of the lab in Cody’s drawing are 25 wide and 24 long

Step-by-step explanation:

First we have to know how much one side of the rectangle measures, for this we have to multiply the measure of Paola by 2 feet

5 * 5ft = 25ft

Now since we have one side of the rectangle and its area we can calculate the other side by dividing the area by the side we have

600ft² / 25ft = 24ft

The rectangle dimensions are 2 sides of 25ft and 2 sides of 24ft

Now we divide the sides by 2 and we pass it to inches to get the measurements of Cody's drawing

25 / 2 = 12.5in

24 / 2 = 12in

The dimensions of the lab in Cody’s drawing are 25 wide and 24 long

step-by-step explanation:

if you want to solve percent error follow these steps.

1. subtract the accepted value from the experimental value.

2. take the absolute value of step 1.

3. divide that answer by the accepted value.

4. multiply that answer by 100 and add the % symbol to express the answer as a percentage.

if you want to solve percent of change just do this.

1. work out the difference (increase) between the two numbers you are comparing.

2. divide the increase by the original number and multiply the answer by 100. if your answer is a negative number then this is a percentage decrease.

hope this : )
