Aposter is shown below: a rectangle is shown. the length of the rectangle is labeled 10 feet. the width of the rectangle is labeled 4 feet. what are the dimensions if the poster is enlarged by a factor of three over two ? 12 ft by 30 ft 2 ft by 5 ft 6 ft by 15 ft 5 ft by 12 ft

The dimensions of the enlarged poster are  by  

Step-by-step explanation:

we know that

The scale factor is equal to the measure of the corresponding side of the enlarged poster divide by the the measure of the corresponding side of the original poster

Let

z-----> scale factor

x------> the measure of the corresponding side of the enlarged poster

y------> the measure of the corresponding side of the original poster

so

In this problem we have

Step 1

Find the length of the enlarged poster

we have

substitute

Step 2

Find the width of the enlarged poster

we have

substitute

therefore

the dimensions of the enlarged poster are  by  

180

step-by-step explanation:

step-by-step explanation:

you can add the two numbers and divide the result by 2. or you can find the gap between the two numbers and add half of this to the smaller number.
