Playground

The land for the construction of the school playground has the shape of a rectangle with a shorter side of 370 m. Its other side is 260 m longer. How many meters of the fence does the school need to buy on the fencing playground?

Correct result:

x =  2000 m

Solution:

$$\begin{gathered} a=370\text{ m } \\ b=a+260=370+260=630\text{ m } \\ x=2\cdot (a+b)=2\cdot (370+630)=2000\text{ m} \end{gathered}$$
