Question

Length and breathe of rectangular field are in ratio 5 : 3 . If the perimeter of the field is 440 m , then find the cost of grassing at the rate of rupees 2.6 per Sq meter. ​

Answer 1

Answer:

22688 rs

Step-by-step explanation:

l = 5x

b = 3x

p = 2(l+b)

440 = 2(8x)

220= 8x

27.5=x

l= 27.5×5 = 137.5

b= 27.5 × 3 = 82.5

area = 137.5 × 82.5

area = 11343.75

cost = 11343.75 × 2.6

cost = 22687.5 rs

cost = 22688 (approx)
