How To Find The Area Of A Letter?

To find the area of any 2D shape such as a letter the following rules apply. You find the area of a square by finding the square of the length of one side. Example: The area of a square with a side length of 2 is 2 x 2 = 4.

You find the area of a rectangle by multiplying the length of one side by the length of its adjacent side. By assigning letters to sides, you can make this easier, where ‘a’ is the length and ‘b’ is the height so Area = a x b. Example: The area of a 3 (a) by 5 (b) rectangle is 3 x 5 = 15.

Compute one-half times the product of the length of the base and the height to find the area of a triangle, where a is the length and b is the height so Area = ½ x a x b. Example: The area of a triangle with base length 4 and height 9 is (1/2) x 4 x 9 = 18.

Multiply the length of the base by the height to find the area of a parallelogram, the same formula for the area of a rectangle. Example: The area of a parallelogram with base length 8 and height 5 is 8 x 5 = 40.

Find the area of a trapezoid by adding the lengths of the parallel lines, then multiplying the sum by one-half the height, where a and b are the lengths of the parallel lines, and c is the height so Area = (a + b) x (½ x c). Example: The area of a trapezoid with height 6 and parallel lines of length 3 and 7 is (1/2) x 6 x (3 + 7) = 30.

Multiply the square of the radius by pi to find the area of a circle, Area = π x r x r. Example: The area of a circle with radius 4, is 4 x 4 x pi = 50.

Determine the area of an ellipse by multiplying pi by the product of the maximal and minimal radii, so where a is the maximum radius, and b is the minimum, Area = πab. Example: The area of an ellipse with maximal radius 9 and minimal radius 6 is 9 x 6 x pi = 170.
