A rectangular piece of land has its length and breadth in the ratio of 5:2 ; if the length of the land is 20cm. find the breadth
Please explain with full process
Answers
Answer:
It is given that,
Ratio in length and breadth of a rectangular piece of land = 5:3
Cost of fencing = ₹9600,
Rate = ₹24 per meter.
We know that,
Perimeter = total cost of fencing / rate per meter,
Substituting the values,
=9600/24
=400 m.
Consider 5x as the length and 3x as the breadth,
Here perimeter = 2(l+b)
Substituting the values,
400=2(5x+3x)
By further calculation,
400=2(8x)
So we get,
400=16x
x=400/16=25.
(i) Length of land = 5x = 5∗25 = 125 m.
Breadth of land = 3x = 3∗25 = 75 m.
(ii) Area = l∗b
Substituting the values,
=125∗75
=9375m
2
.
(iii) Cost of levelling at the rate of ₹60 per m

= 60∗9375
= ₹ 5,62,500.

Answer:
Let the length be 5x and breath be 2x
5x=20
x=4cm
breadth=2×4=8cm
Step-by-step explanation:
Hence 8cm is the right answer
