Process 81358

Teo went around the pool twice. He took 160 steps in the process. He took 25 steps along the length. How much area does the pool take up, and how long is Tro's stride?
0.5m?

Correct answer:

S =  93.75 m²

Step-by-step explanation:

$$\begin{gathered} n=160/2=80 \\ a=25 \\ n=2(a+b) \\ b=n/2-a=80/2-25=15 \\ k=0.5\text{m} \\ x=k\cdot a=0.5\cdot 25=\frac{25}{2}=12.5\text{m} \\ y=k\cdot b=0.5\cdot 15=\frac{15}{2}=7.5\text{m} \\ S=x\cdot y=12.5\cdot 7.5=93.75{\text{m}}^2 \end{gathered}$$
