Garden

The rectangular garden has dimensions of 27 m and 30 m. Peter and Katka split it in a ratio of 4:5. How many square meters did Katkin measure part of the garden?

Correct answer:

K =  450 m²

Step-by-step explanation:

$$\begin{gathered} a=27\text{m} \\ b=30\text{m} \\ S=a\cdot b=27\cdot 30=810{\text{m}}^2 \\ P=4/(4+5)\cdot S=4/(4+5)\cdot 810=360{\text{m}}^2 \\ K=5/(4+5)\cdot S=5/(4+5)\cdot 810=450{\text{m}}^2 \end{gathered}$$
