The turfing of rectangular field 85 paise per square metre is rupees 624.75 find the perimeter of the field if it side are in the ratio 5 ratio 3
Answers
Answer:
Step-by-step explanation:
Turfing per m^2 = 0.85
Total cost of turfing = 624.75
As the sides are in the ratio 5:3
Let it be 5x and 3x respectively,
According to given condition,
0.85 * 5x * 3x = 624.75
x^2 = 49
x = 7,-7
Since the dimensions cannot be negative.
Therefore x= 7m
The dimensions are :
Length= 5x = (5*7) = 35m
Breadth= 3x=(3*7)= 21m
Hence perimeter = 2*(35+21)
= 2*56 = 112m
Answer:
Length=2.295
Breadth =1.377
Step-by-step explanation:
Let 5:3 be the common multiples of x
Therefore we get 2 numbers 5x and 3x
Perimeter of rectangle =2(l+b)
=2(5x+3x)
=2(8x)
=16x
Now total cost = perimeter(cost of turfing 1square m)
Therefore
624.75=16x (85 paise)
624.75÷85=16x
7.35=16x
7.35÷16=x
0.459=x
Therefore 5x=5(0.459)
=2.295
And 3x=3(0.459)
=1.377
