A scale drawing of a rectangular park is 5 inches wide and 7 inches ong. The actal prake is 280 yards long. What is the area of the actual park, in square yards?

Given:

A scale drawing of a rectangular park is 5 inches wide and 7 inches long.

The actual park is 280 yards long.

To find:

The area of the actual park.

Solution:

Length of drawing = 7 inches

Length of actual park = 280 yards

The scale factor is

7 inches : 280 yards

1 inches : 40 yards

The width of the drawing is 5 inches. So, the width of actual part is

The area of the actual park is

Therefore, the area of the actual park is 56000 sq. yards.

The answer is

Step-by-step explanation:

You use the formula

Which will give you 3. So the slope is 3/

Then you continue with the equation-   (m represents the slope which is 3) We use then use any point but I used (4,2) to plug into the equation.

After using that equation, you get the y-intercept as -10. So, the equation is
