Question

the length and breadth of a rectangular field are in the ratio 7 is to 5 and its perimeter is 384 find the cost of reaping the field at rupees 1.25 per square metre​

Answer 1

let length= 7x and breath = 5x

perimeter of rectangle = 2 ( l+ b)

384= 2( 7x + 5x)

384/2= 12x

192/12= x

x = 16

now area of rectangle = l× b

7×16×5×16

112×80

8960m²

cost of 1m²= 1.25

cost of 8960m²= 8960× 1.25

= ₹11200
