The perimeter of the rectangle is 40 cm.Find the sides of the rectangle if one side is 7cm larger

The perimeter of the rectangle is 40 cm.Find the sides of the rectangle if one side is 7cm larger than the other side of the rectangle

To find the sides of a rectangle, we take the smallest side as X, and the largest as 7 + X (according to the condition).

Let’s write the equation:

2 * (7 + x) + 2 * x = 40 (2 in our case is the number of sides of the rectangle);

Let’s multiply:
14 + 4X = 40;
4X = 26;
X = 26/4;
X = 6.5 – the smaller side;
7 + 6.5 = 13.5 – large side.
