Let’s find the length of the rectangle.
The area must be divided by the width, we get:
120: 10 = 12 (cm) – the length of the rectangle.
Now we find the perimeter of the rectangle,
P = 2 (a + b)
P = 2 (12 + 10) = 44 (cm) – the perimeter of the rectangle.
Answer: 12 cm length of the rectangle, 44 cm perimeter of the rectangle.
