FAQs on Understanding: Area of Squares and Rectangle Video Lecture - Class 7

1. What is the formula to calculate the area of a square?
Ans. The formula to calculate the area of a square is side length multiplied by itself, or A = s^2, where A represents the area and s represents the side length.
2. How do you find the area of a rectangle?
Ans. To find the area of a rectangle, you need to multiply the length of the rectangle by its width. The formula is A = l x w, where A represents the area, l represents the length, and w represents the width.
3. Can the area of a square be greater than the area of a rectangle with the same side length?
Ans. No, the area of a square cannot be greater than the area of a rectangle with the same side length. Since a square has all sides equal in length, it is a special type of rectangle. The area of a square is equal to the side length squared, while the area of a rectangle is equal to the product of its length and width. Therefore, the area of a square will always be equal to or smaller than the area of a rectangle with the same side length.
4. What are the units used when expressing the area of squares and rectangles?
Ans. The units used to express the area of squares and rectangles depend on the units used for the side length, length, and width. For example, if the side length, length, or width is measured in centimeters, the area will be expressed in square centimeters (cm^2). Similarly, if the measurements are in meters, the area will be in square meters (m^2), and so on.
5. Is the area the only factor to consider when comparing squares and rectangles?
Ans. No, the area is not the only factor to consider when comparing squares and rectangles. Other factors to consider include the perimeter, which is the sum of all the sides of the shape, and the shape's proportions. While squares have equal sides and angles, rectangles have different side lengths and angles. Therefore, the decision of which shape to use depends on the specific requirements of the situation.
