Question

The perimeter of a rectangle is 60 cm. The ratio of length to width is 3:2 . Find the length and width of the rectangle.

Answer 1

x = length

y = width

---

2x + 2y = 60

x/y = 3/2

2x = 3y

---

put the system of linear equations into standard form

---

2x + 2y = 60

2x - 3y = 0

---

solution:

length = 18 cm

width = 12 cm

Hope this helps!
