Question

The length and breadth of a rectangular piece is in ratio 5:3 if the total cost of fencing is at rate of rupees 24 per meter is rupees 9600 find its 1. length an d breadth 2. Its area 3. Cost of levelling at the rate of rupees 60 per meter square

Answer 1

Answer:

Step-by-step explanation:

let length be 5x and breadth be 3x

2(l+b)*24=9600

8x=200

x=25

l=25*5=125m

b=25*3=75m

area = l*b =9375m2

cost=9375*60=562500 rs

Answer 2

$\huge \pink{\bf AnSwer }$

Length and the breadth of a rectangle are of the ratio 5:3

Cost of fencing is ₹24 per m

Total cost = 9000

Length & Breadth of the rectangle

Solution

Let,

Length = 5x

Breadth = 3x

✭ Perimeter

→ Perimeter = Total Cost/Cost per m

→ Perimeter = 9000/24

→ Perimeter = 400 m

✭ Finding x

→ Perimeter = 2(l+b)

→ 400 = 2(5x+3x)

→ 400/2 = 8x

→ 200 = 8x

→ 200/8 = x

→ x = 25

✭ Length and Breadth

→ Length = 5x = 5×25 = 125 m

→ Breadth = 3x = 3×25 = 75 m
