    Answer:

     Length: \frac{25}{2} =12.5 \\Breadth: \frac{26}{5} = 5.2

    Perimeter of rectangle: 2(l+b)

    = 2(12.5+5.2)

    = 2(17.7)

    = 35.4m

    Area of Rectangle: l  \times b \\       = 12.5 \times 5.2\\       = 65m²

    Now, \\Area \: of\:  4\: small\: sq.\: flower\: beds\: of\: side\: 1 m: \\Area\: of\: 1\: small\: sq.\: flower\: beds= s \times s \\                        = 1 \times 1 \\                        = 1m²

     Area\: of\: 4 Small\: sq.\: flower\: beds= 4 \times 1 \\ = 4m² = Used\: Area

    Unused Area= Total Area – Used Area

    Unused Area = 65m² – 4m²

    Unused Area = 61m²
