The perimeter of the triangle is 41 inches. the perimeter of the rectangle is 66 inches.
(note: pictures are not drawn to scale)
part a: write a system of equations to determine x and y.

part b: solve the system of equations. use your solution to determine the length and width of the rectangle.

Part A)  The system of equations is equal to

Part B)

The length is

The width is

Step-by-step explanation:

Part A)

we know that

The perimeter of the triangle is equal to the sum of the length of its three sides

In this problem

-----> equation A

The perimeter of rectangle is equal to

In this problem

------> equation B

Part B)

Using a graphing tool

Solve the system of equations

We know that

The intersection point both graphs is the solution of the system of equations

The intersection point is

see the attached figure

step 3

Find the length and width of the rectangle

The length is 3x

The width is 7y

i need the table so i can see
