1.	The length and breadth of a rectangle field are in the ratio 3:2. If the area of the field is 3456m sq. Find the cost of fencing field at Rs 4/m
Answer» Step-by-step explanation: ratio = 3:2 Let the COMMON factor be x. length(L) = 3X breadth(b) = 2x. area = l×b (3x)(2x) = 3456 m² 6x² = 3456. x² = 576. x = 24 m. length = 3(24) = 72. breadth = 2(24) = 48. perimeter = 2(l + b) = 2(72 + 48) = 240 m. cost for fencing 1 m. = ₹4. cost for fencing 240 m = 4 × 240 = ₹ 960.

The length and breadth of a rectangle field are in the ratio 3:2. If the area of the field is 3456m sq. Find the cost of fencing field at Rs 4/m

Answer»

Step-by-step explanation:

ratio = 3:2

Let the COMMON factor be x.

length(L) = 3X

breadth(b) = 2x.

area = l×b

(3x)(2x) = 3456 m²

6x² = 3456.

x² = 576.

x = 24 m.

length = 3(24) = 72.

breadth = 2(24) = 48.

perimeter = 2(l + b) = 2(72 + 48)

= 240 m.

cost for fencing 1 m. = ₹4.

cost for fencing 240 m = 4 × 240 = ₹ 960.
