The complete question is

A dance floor has a perimeter of 60 meters. The dance floor is 20 meters long. Use this information to  help you follow the directions below.

1. Write an equation using variables to represent the perimeter of the dance floor. 2. Solve the equation to find the dimensions of the dance floor. 3. Write an equation using variables to represent the area of the dance floor. 4. Solve the equation to find the area of the dance floor.

Let

L-------->  the length side of the dance floor

W-------> the width side of the dance floor

P------> Perimeter of the dance floor

A-----> area of the dance floor

we know that

the perimeter of the dance floor is

therefore

the answer Part 1) is

The equation to represent the perimeter of the dance floor is

Part 2) Solve the equation to find the dimensions of the dance floor.

In this problem we have

Substitute in the Perimeter formula

therefore

the answer part 2) is

the dimensions of the dance floor are

the length side of the dance floor is

the width side of the dance floor is

Part 3) Write an equation using variables to represent the area of the dance floor

we know that

the area of the dance floor is

therefore

the answer part 3) is

The area of the dance floor is

Part 4) Solve the equation to find the area of the dance floor.

we know that

Substitute in the formula of area

therefore

the answer art 4) is

the area of the dance floor is

addition

step-by-step explanation:

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
