Area
Area is the size of a surface. There are special formulas for certain shapes. Area of the rectangle is obtained by the product of length and width. Area of the square is given by the product of its sides. Area of the circle is solved by multiplying pi with the radius squared.
Answers:
- A = 120 cm²
- A = 12 cm²
- A = 75 cm²
- A = 90 m²
- A = 144 m²
Solutions:
1. Area of the Parallelogram = base x height
A = 12 cm x 10 cm
A = 120 cm²
2. Area of the Triangle = [tex]\frac{1}{2}[/tex] base x height
A = [tex]\frac{1}{2}[/tex] (6 cm x 4 cm)
A = [tex]\frac{1}{2}[/tex] (24 cm²)
A = [tex]\frac{24}{2}[/tex] cm²
A = 12 cm²
3. Area of the Trapezoid = [tex]\frac{1}{2}[/tex] (base₁ + base₂) x height
A = [tex]\frac{1}{2}[/tex] (10 cm + 20 cm) x 5 cm
A = [tex]\frac{1}{2}[/tex] (30 cm) x 5 cm
A = [tex]\frac{30}{2}[/tex] cm x 5 cm
A = 15 cm x 5 cm
A = 75 cm²
4. Area of the Rectangle = length x width
A = 15 m x 6 m
A = 90 m²
5. Area of the Square = side x side
A = 12 m x 12 m
A = 144 m²
