The perimeter of the triangle is 41 inches. The perimeter of the rectangle is 66 inches.

Korolek [52]

Answer:

Part A) The system of equations is equal to

$41=4x+7y$

$33=(3x+7y)$

Part B)

The length is $24\ in$

The width is $9\ in$

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

$41=x+3x+7y$

$41=4x+7y$ -----> equation A

The perimeter of rectangle is equal to

$P=2(L+W)$

In this problem

$66=2(3x+7y)$

$33=(3x+7y)$ ------> 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

$41=4x+7y$

$33=(3x+7y)$

The intersection point is $(8,9/7)$

see the attached figure

$x=8\ in$

$y=(9/7)\ in$

step 3

Find the length and width of the rectangle

The length is 3x

$3*8=24\ in$

The width is 7y

$7*(9/7)=9\ in$
