Question

Design an algorithm to calculate the area of rectangle​

Answer 1

To calculate the area of a rectangle, measure the length and width, then multiply these dimensions together. The area is expressed in square units, and proportions can be used to compare different areas.

Step-by-step explanation:

To design an algorithm to calculate the area of a rectangle, we follow these simple steps:

1. Measure the length (l) of the rectangle.
2. Measure the width (w) of the rectangle.
3. Multiply the length by the width to get the area (A): A = l × w.

For example, if a rectangle has a length of 5 meters and a width of 3 meters, the area will be 15 square meters since 5 × 3 = 15.

Remember that the area is always expressed in square units, based on the units used for length and width. When comparing areas using a scale, we can use proportions to evaluate the relation between different rectangles or spaces.
