Question

The length and breadth of a rectangular field are in the ratio 3 : 2. If the perimeter of the field is 250 m,
find the cost of reaping the field at 15 per 50 m².
​

Answer 1

Answer:

length = 75m

breadth = 50m

Area=3750m²

cost = 3750/50*15= ₹1125

Answer 2

Answer:

The cost of reaping of the rectangular field is 1125Rs

Step-by-step explanation:

l=3x; b=2x.

p=2(l+b) = 2(3x+2x) = 250

= 10x = 250

x = 25

l=3x = 3(25) = 75

b=2x = 2(25) = 50

Area of rectangular field,

A = lb = (75)(50) = 3750m²

The cost of reaping the field at 15 per 50 m²,

for 3750m², (3750/50)(15) = 75(15)= 1125Rs
