The perimeter of the square area is 36m. What is the length of the side of the court. The length of the rectangular section is 16m

The perimeter of the square area is 36m. What is the length of the side of the court. The length of the rectangular section is 16m. What is the width of this section if its perimeter is 50 m?

The perimeter is the sum of the lengths of all sides of a geometric shape.
The perimeter of a square is found by the formula:
P = a 4, where a is the side length of the square.
The perimeter of the rectangle is calculated using the formula:
P = (a + b) 2, where a is the length of the rectangle, b is the width of the rectangle.
If the perimeter of a square site is 36 meters, then in order to find the length of the side of the site, it is necessary to divide the perimeter by 4:
a = P: 4;
a = 36: 4;
a = 9 meters.
If the length of a rectangular section is 16 meters, and the perimeter is 50 meters, then by transforming the formula for the perimeter of a rectangle, you can find out the width of this section:
b = P: 2 – a;
b = 50: 2-16;
b = 25-12;
b = 13 meters.
