please D part with expilation

Answer 1

Answer:

Answer Fencing is done at the perimeter so, perimeter of rectangular park = 2(l + b) = 2(350 + 250) Rightarrow2*600=1200m Rate of fencing per meter=Rs. 18.50 .:: Rate of fencing .00m=Rs.8.50*1200 = Rs.22 22, 20

Step-by-step explanation:

this is not a answer but this is a way you should find their answers try it

Answer 2

Solution!!

Length = 15 m

Breadth = 10 m

(A) Total length of wire required for fencing the field = Perimeter of the field

Perimeter = 2(Length + Breadth)

Perimeter = 2(15 m + 10 m)

Perimeter = 2(25 m)

Perimeter = 50 m

Total length of wire required for fencing = 50 m

(i) 50 m

(B) Area of the field = Length × Breadth

Area = 15 m × 10 m

Area of the field = 150 m²

(iii) 150 m²

(C) Ratio between area and perimeter = 150/50

Ratio = 3/1

Ratio = 3:1

(iii) 3:1

(D) Cost of fencing 1 metre = Rs 75

Cost of fencing 50 metre = Rs 75 × 50

Cost of fencing the field = Rs 3750

(iv) Rs 3750
