Question

Ratio of length and breadth of a rectangular Garden is 4:3 if its area is 4800 m square find the cost of fencing it with wire four times at the rate of 1.75 per metre

Answer 1

Answer:

Step-by-step explanation:

Answer 2

Step-by-step explanation:

Ratio of l and b = 4:3

so,the length of the garden= (4x) unit

and the breadth of the garden =(3x)unit

since,area of rectangular garden =4800m sq

length × breadth=4800m sq

4x×3x=4800

12×sq=4800

xsq=4800/12

xsq=400

X sq =(20) sq

X=20

so the length of garden=4×20=80m

and breadth of garden = 3×20=60m

so, the perimeter of the rectangular garden= 2×(l+b)

2×(80+60)m

2×140m=280m

length of wire required for fencing the garden four times=4×280m=1120m

so,the cost of fencing=₹(1120×1.75)=₹1960

Answer

hence, the cost of fencing the rectangular garden is =₹1960
