This section is catered to finding the area enclosed by rectangles, squares, triangles, parallelograms, trapeziums, and circles.
The area of a rectangle, A = Lw
Where, L is the length of the rectangle
And, w is the width of the rectangle.
Squares are special cases of rectangles. All the sides of a square are equal.
The area of a square, A = L2
Where, L is the length of a side of the square.
Where, b is length of the base of the triangle
And, h is the height of the triangle.
The area of a parallelogram, A = bh
Where, b is the length of the base of the parallelogram
And, h is the perpendicular height of the parallelogram.
Where, a is the length of one parallel side of the trapezium
b is the length of the second parallel side of the trapezium
And, h is the perpendicular height (distance between the 2 parallel sides) of the trapezium.
The area of a circle, A = πr2
Where, r is the radius of the circle
Area, A = πr2
