Find area of rectangles

Area of a rectangle is the amount of two-dimensional space it covers, measured in square units; it can be found by multiplying the length by the width because an array of unit squares has equal rows and columns. The dimensions and area must use compatible units, and area must not be confused with perimeter; the focus is on rectangles with whole-number side lengths rather than generalized formulas or fractional and decimal dimensions.

Detailed Explanation: Find area of rectangles

Area tells how much space is inside a rectangle. You can find it by multiplying the length by the width:

Area=length×width\text{Area}=\text{length}\times\text{width}

For example, find the area of a rectangle that is 88 centimeters long and 33 centimeters wide.

  1. Identify the length and width:

    • Length: 8 cm8\text{ cm}
    • Width: 3 cm3\text{ cm}

  2. Multiply:

8×3=248\times 3=24

  1. Write the answer in square units. Since the measurements are in centimeters, use square centimeters:

24 square centimeters\boxed{24\text{ square centimeters}}

The rectangle has an area of 24 cm224\text{ cm}^2. This means it could be covered by 2424 unit squares, arranged in 88 rows of 33 squares. Area measures the space inside; it is not the distance around the rectangle, which is called perimeter.
