Square-shaped 62174

We need 25 dm2 of soil for each seedling, we planted 30 seedlings on a square-shaped bed, and there is another 1.5 m2 of free soil for the spacing between them. How much mesh do we need to buy to fence the flowerbed?

Correct answer:

x =  12 m

Step-by-step explanation:

S1=25 dm2 m2=25:100  m2=0.25 m2 S2=1.5 m2  S=30 S1+S2=30 0.25+1.5=9 m2  S=a2  a=S=9=3 m  x=4 a=4 3=12 m
