Here is a sequence of increasingly large similar rectangles.

For each iteration, the new rectangle width is larger than the previous rectangle width at a ratio of 5:2

1. If the area of the first rectangle is 20cm^{2} and the width of the third rectangle is

15.625 cm, find the length and width of the second rectangle.

2. What is the area of the 10th rectangle in the sequence?

Hiya, this is probably wrong but is 1) 6.25 width and area 125 2) 291036987.3

I used the geometric sequence formula for everything :’)

it’s correct 🙂 Part 2 looks prettier if you switch to m^2. But not much prettier!
