Question

The length of a rectangle is 5 times the width. The perimeter of the rectangle is 60 inches. Let x represent the length and let y represent the width. Write the system of linear equations that represent this situation and what is the area of the rectangle?

Answer 1

x = 5y (*2) because there are four total sides
2x = 10y
so plug in y in the equation
60 = 10y + 2y
60 = 12y
5 = y
x = 5(5)
x = 25

So the length is 25 units, and the width is 5 units
