Answer 1

P=(8+5)*2=26 м 
S=8*5=40

Answer 2

Calculation of the Rectangle's Area and Perimeter

To find the area and perimeter of a rectangle, we need to know its length and width. In this case, the length of the rectangle is 8 meters, and the width is 5 meters.

Area of a Rectangle: The area of a rectangle is calculated by multiplying its length by its width. So, the formula for finding the area (A) of a rectangle is:

A = length * width

Substituting the given values, we have:

A = 8 * 5 = 40 square meters.

Therefore, the area of the rectangle is 40 square meters.

Perimeter of a Rectangle: The perimeter of a rectangle is calculated by adding the lengths of all its sides. For a rectangle with sides of length a and b, the formula for finding the perimeter (P) is:

P = 2 * (a + b)

Substituting the given values, we have:

P = 2 * (8 + 5) = 2 * 13 = 26 meters.

Therefore, the perimeter of the rectangle is 26 meters.

To summarize: - The area of the rectangle is 40 square meters. - The perimeter of the rectangle is 26 meters.
