Question

the length and breadth of a rectangular field at 120 M and 75 M respectively find (i) the area of the field and the cost of turfing it at Rs 15 per metre square. ( ii) the perimeter of the field and the cost of fencing it at Rs 40 per m. explain it with picture

Answer 1

(i) = 120*75*15 = 13500
(ii) = 2*195*40 = 15600

Answer 2

Answer:

Step-by-step explanation:

Given :-

Length of the field = 120 m

Breadth of the field = 75 m

Solution :-

(i) Area of the field = L × B

= L × B

= (120 × 75) m²

= 9000 m²

Cost of turfing the field = ₹ 15

= ₹ (9000 × 15)

= ₹ 135000.

(ii) Perimeter of the field = 2(L + B)

= 2(L + B)

= 2(120 + 75)

= 390 m

The cost of fencing = ₹ 40.

= ₹(390 × 40)

= ₹ 15600.
