Study Notes
- Chapter Six focuses on finding the area of rectangles, squares, and triangles.
- Competencies developed in this chapter can be applied to building constructions, textile and dressmaking, and various real-life applications.
The Concept of Area
- Area refers to the surface region of a shape.
- Area is determined by dividing a shape into equal squares, counting them, or using formulas and measurements.
- Area is measured in metric units, including square meters (m²), square centimeters (cm²), and square millimeters (mm²).
Area of a Rectangle
- The area of a rectangle is the entire surface region enclosed within its boundaries.
- To calculate the area of a rectangle, multiply its length by its width (Area = length × width).
- Example: A book with a length of 30 cm and a width of 20 cm has a surface area of 600 cm².
- Example: A rectangle is 9 cm long and 5 cm wide, its area is 45 cm².
- Example: A rectangle with a width of 40 cm and a length of 90 cm has an area of 3600 cm².
Area of a Square
- Area of a square is obtained by multiplying the length by the width of the square
- Recall that all sides of a square have equal length
- Area of a square = length x width or length x length
- Example: A square that is 9 cm long and 9 cm wide, has an area of 81cm^2
- Example: A square field that is 70 metres has a area of the field of 4900m^2
Area of a Triangle
- The area of a triangle is the surface region enclosed within its boundaries.
- The area of a triangle is calculated as half of the product of its base and height (Area = ½ × height × base).
- Example: A triangle with a base of 10 cm and a height of 7 cm has an area of 35 cm².
- Example: A triangle with a height of 15m and a base of 30m is 225m^2
- Example: A triangle with a height of 12cm and a base of 26cm, has an area of 156cm^2
