Your answe​

Answer 1

Answer:

(a) Length = 13 m

(b) Cost of fencing = ₹312.5

Step-by-step explanation:

(a) Given:

   Area of the rectangular plot = 156m²

   Breadth = 12m

   Area of a rectangle = Length × Breadth

⇒ 156m² = Length × 12m

⇒ Length = $\frac{156}{12}$ m

⇒ Length = 13 m

(b) Cost of fencing at the rate of 1m = ₹6.25

    Perimeter of the rectangular plot = 2(length + breadth)

    = 2(13+12)

    = 2(25)

    = 50m

    Cost of fencing at the rate of 50m = 50 × ₹6.25

                                                              = ₹312.5
