Find the perimeter of the rectangle if one of its sides is 4.3 cm and the area is 9.03 cm.

The area of a rectangle is equal to the product of its two adjacent sides. Find the other side knowing that it is 4.3 cm long.

9.03: 4.3 = 2.1 (cm) – the width of this rectangle.

Let’s find the perimeter of this shape. It is equal to twice the sum of the length and width, which are 4.3 and 2.1 cm, respectively.

(4.3 + 2.1) * 2 = 6.4 * 2 = 12.8 (cm) – the perimeter of this rectangle.

Answer: 12.8 (cm) is the perimeter of this triangle.
