We can make a large triangle like the one shown in the attached image by drawing smaller shapes. 

To make a large triangle using 5 smaller shapes, the following small shapes were used: 

- Rhombus
- Triangle
- Square
- Triangle
- Triangle 

There are multiple ways that these shapes could be rearranged to form such a triangle, the attached image is simply an example.

If you need an equation, it would be y=2x+8, y would be how long it grew, x being weeks.if you need how long he was asleep, it would be 4 weeks if he started with no beard, the equation would be x=8÷2if he did have a beard before hand, the equation would be 2w+x=8
