Given :-

  • Length of flower bed = 7 m

  • Perimeter of boundary = 22 m

To Find :-

  • Breadth
  • Area

Solution :-

As we know that

[tex]\sf \blue{Perimeter = 2(l + b)}[/tex]

  • 22 = 2(7 + b)

  • 22 = 14 + 2b

  • 22 - 14 = 2b

  • 8 = 2b

  • [tex]\sf \: \dfrac{8}{2} = b[/tex]

  • [tex]\bold{\boxed{b=4}   }[/tex] 

Breadth = 4 m.

Now,

[tex]\sf \orange{Area = l \times b}[/tex]

  • [tex]Area = 7 \times 4[/tex]

  • [tex]\sf \: Area = 28 \: {m}^{2}[/tex]

Area=28[tex]\bold{ m^2  }[/tex]
