Area and Perimeter Practice

The perimeter of a rectangle is the total distance around the rectangle, calculated by adding the lengths of all four sides. Formula: P = 2(length + width).

The area of a rectangle is the amount of space inside it, calculated by multiplying the length by the width. Formula: A = length × width.

The perimeter of a square is calculated by adding the lengths of all four sides or using the formula: P = 4 × side length.

The area of a square is calculated by squaring the length of one of its sides. Formula: A = side length × side length.

The perimeter is 30 meters. (P = 2(10 + 5) = 30).

The area is 50 square meters. (A = 10 × 5 = 50).

Area measures the space inside a shape, while perimeter measures the distance around it. They are related but represent different properties.

The missing side lengths are 15 meters.

Square units measure area (e.g., square meters), while linear units measure length or distance (e.g., meters).

Divide the area by the known side length. Formula: missing length = Area ÷ known side length.
