The area of the rectangle is 238 cm2, the length of one of the sides of this rectangle is 17 cm, find the perimeter of this rectangle.

From the condition, we know that the area of the rectangle is 238 cm2, and we also know that the length of one of the sides of this rectangle is 17 cm. In order to find the perimeter of this rectangle, let’s first of all find the length of the second side.

Let’s remember the formula for finding the area of a rectangle:

S = a * b;

Substitute the known values and solve the equation:

17a = 238;

a = 238: 17;

a = 14 cm second side of the rectangle.

We are looking for the perimeter by the formula:

P = 2 (a + b) = 2 (14 + 17) = 2 * 31 = 62 cm.

Answer: the perimeter is 62 cm.
