Answer:
Geography.
Step-by-step explanation:
Geographers use many tools in their work. Maps, globes, photos, satellite images, and models are all tools that geographers might use. Geographers who study ancient Egypt might want to know how the people used the Nile River. For example, the Nile is known to flood. Geographers might study how people dealt with flooding. They might also want to know if or how they used floods to help them.

We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12
The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.
