Answer both questions you will be marked the brainliest if u r the first to answer

Answer(5):

Given scale is 3 in : 8 ft

that mans 3 inch = 8 feet

or 1 inch = 8/3 feet

Given that length of the rectangle = 6.5 in

Then actual length of the room = 6.5*(8/3) = 17.3333

Given that width of the rectangle = 5 in

Then actual width of the room = 5*(8/3) = 13.3333

Now we have to find the area so we will plug the values into

Area = Length x Width = 17.3333 x 13.3333 = 231.11008889

So final answer rounded to nearest tenth is given by:

Length = 17.3 ft

Width = 13.3 ft

Area = 231.1 square ft

Answer(6):

Given scale is 3 in : 5 ft

that mans 3 inch = 5 feet

or 1 inch = 5/3 feet

Given that length of the rectangle = 13.2 in

Then actual length of the room = 13.2*(5/3) = 22

Given that width of the rectangle = 6 in

Then actual width of the room = 6*(5/3) = 10

Now we have to find the area so we will plug the values into

Area = Length x Width = 22 x 10 = 220

So final answer rounded to nearest tenth is given by:

Length = 22.0 ft

Width = 10.0 ft

Area = 220.0 square ft

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.

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 : )
