Answer:
Area of a square = Length × Length
Area of a triangle = 1/2 base × height
Area of a rectangle = Length × breadth
Area of a parallelogram = base × height
Area of a trapezoid = 1/2 × sum of parallel sides × height
Area of circle = π × square of the radius
Area of ellipse = π × product of major and minor radii
Area of equilateral triangle = 1/2 base × height
Step-by-step explanation:
The area of a square is calculated by multiplying the length by itself.
The area of a triangle is calculated by multiplying half the base of the triangle by its height
The area of a rectangle is found by multiplying the length of the rectangle by its breadth
The area of a parallelogram is calculated by multiplying the base of the parallelogram by its height
The area of a trapezoid is found by multiplying half the sum of the two parallel sides by its height
The area of a circle is calculated by multiplying pi by the square of the radius of the circle
The area of an ellipse is found by multiplying pi by the product of the major and minor radii of the ellipse
The area of an equilateral triangle is calculated by multiplying half the base of the triangle by its height. The height is calculated using Pythagoras theorem
