The rectangle shown has a perimeter of 56 cm and the given area. It’s length is 4 more than 3 times it’s width write and solve a system of equations to find the dimensions of the rectangle

The length is 22 cm and the width is 6 cm

Step-by-step explanation:

Let:

Equations:

Solve Using Substitution:

We know that l is 3w + 4. So input 3w + 4 for l in the top equation.

Plugin New Info:

Now that we solved for w, we can solve for l by inputting the value of w in the second equation

answer4 to the second power is 16

and 4 to the third power is 64,
