Question

The length and breadth of a rectangular field are in the ratio 4:3. If the perimeter of the field
is 350 m. Find the area of the rectangle. Also, find the cost of leveling the field at the rate of
35 per metre square.
fir 20 cm cind the breadth and area of the​

Answer 1

Answer:

area = 7500m^2

cost of leveling =  rs.262,500

Step-by-step explanation:

perimeter = 2(l+b)

350 = 2(4x+3x)

350 = 2*7x

350 = 14x

x= 25

length = 100m

breadth = 75m

area = 7500m^2

cost of leveling =  rs.262,500

Answer 2

Answer:

let us assume the length (L) of rectangle is = 4x

and. breadth (B) of rectangle is = 3x

perimeter of the rectangle is = 2(L+B) = 2(4x+3x) =14x

according to question

perimeter of the field is = 350m

14x= 350m

x= 350/14

x= 25

then length = 4*25= 100m

and breadth = 3*25= 75m

area of rectangle is = L*B = 100*75= 7500m^2

cost of leveling the field of one meter square is = 35

then the cost of leveling the field of 7500 msaq. is= 35*7500 = 262500rs.
