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?

Result

x =  2000 m

Solution:

a=370 m b=a+260=370+260=630 m  x=2⋅ (a+b)=2⋅ (370+630)=2000=2000  m a = 370 \ m \ \\ b = a + 260 = 370 + 260 = 630 \ m \ \\ \ \\ x = 2 \cdot \ (a+b) = 2 \cdot \ (370+630) = 2000 = 2000 \ \text{ m }
