Area of the big triangle (shaded area and small tris for below) is 36 * 51 divided by 2 (area of triangle is base * height over 2). this would give you 918.
area of the small triangle below is 51 * 11 divided by 2 (see above), which is 280.5.
shaded shape area is the big triangle shape minus the small triangle below, which is 918-270.5, which is 637.5 units.

Given the geometric progression below

The nth term of a geometric progression is given below

From the geometric progression, we can deduce the following

To find the value of r, we will take ratios of two consecutive terms

To find the 9th term of the geometric, we will have that;

Hence, the 9th term of the geometric progression is 1953125
