Answer 1

Answer:

$120\ m$ of wire is needed to fence the garden .

Step-by-step explanation:

To find : many meters of wire is needed to fence the garden .

Given : A square garden has a side of 30 m.

Solution :

• As per given data we know that , a square garden has a side of 30 m.  
• To find many meters of wire is needed to fence the garden . We first find perimeter of square .
• We know that all four sides of square are equal .
• If ' $a$ ' is the side of square then perimeter of square is given by,
• Perimeter of square $=4 a$
• Therefore, by substituting the value in above formula we find perimeter.
• Perimeter of garden =  $4\times 30$

                                          $= 120\ m$  

• Meters of wire needed to fence the garden = Perimeter of garden

                                                                                 $= 120\ m$
