Court field comparison

The tennis court measures 40.20 meters. The football field measures 40.90 meters. How many times is the football field compared to the tennis court?

Final Answer:

n =  4.5

Step-by-step explanation:

$$\begin{gathered} a=40\text{m} \\ b=20\text{m} \\ c=40\text{m} \\ d=90\text{m} \\ {S}_1=a\cdot b=40\cdot 20=800{\text{m}}^2 \\ {S}_2=c\cdot d=40\cdot 90=3600{\text{m}}^2 \\ n=S_2/S_1=3600/800=\frac{9}{2}=4\frac{1}{2}=4.5 \\ n=d/b \end{gathered}$$
