How can you find the perimeter and area of a rectangle?

To find the perimeter of a rectangle, add the sum of the length and width of the rectangle and multiply by 2. The formula for the perimeter of a rectangle looks like this: P = (a + b) · 2, a – length, b – width of the rectangle. To find the area of a rectangle, you need to multiply the length of the rectangle by the width of the rectangle. S = a * b. Also, for the correct solution, it is necessary to check that the sides of the rectangle are expressed in the same units of length. (see, meter).
